Cream cheese might be an especially good option if you're making biscuits and gravy (where the biscuit is more of a vessel for the gravy anyway). Almost sounds like what you'd expect with a gluten free flour. on Step 5, Enjoyed your experiments very muchI've been experimenting myself, but every variation I try seems to turn out crumbly which I hate. The caramelisation of different sugars occurs at differen… Making biscuits is basically composed of seven steps: Most of these steps are pretty straightforward, but here are some tips and tricks I've learned after making about a zillion biscuits: Baking powder is a field of contention. Bake at a higher temperature... not because it makes a big difference in the final biscuit, but because you get to eat your biscuits sooner. What Is Cream of Tartar or Potassium Bitartrate? But if you want to save a few bucks and a few calories, margarine is a great alternative that may even make the biscuits taste better. What reasons did the un-witting margarine lovers give? Note: Metric conversions (thanks to ZaKKoS for writing these up): First Prize in the Explore Science Contest, Participated in the Apocalypse Preparedness Contest. My favorites were probably the ones in the middle (with 1 cup of liquid per 2 cups of flour), but that was by a very narrow margin, and my decision may have been influenced by the fact that a 1:2 ratio is easy to remember. (I actually use the plain greek yogurt I always have in the fridge, mixed about 1/2 and 1/2 w/milk; close enough! Once you get the dough right, the biscuits should come out of your cutter just fine. A standard cake recipe typically includes flour, a type of sweetener, eggs, some kind of fat, a liquid, a leavening agent to help it rise and flavoring (like vanilla, cocoa powder or cinnamon) [source: What's Cooking America].The ingredients interact with each other … The biscuit with very little butter wasn't as soft and flaky, but it was more structurally sound. Thanks for asking! Thanks, Answer How does the amount of liquid affect the final product? Baking cookies seems simple, especially if you cook pre-made cookie dough, but it's really a set of chemical reactions. Both were baked at 425 F. There were five taste testers (who did not know what was in the biscuits they were tasting): Milk and water both seem to work fine... there's no clear advantage of one over the other. Roll with a pin or pat with your hands until it's about one inch thick. Turns out American biscuits are basically sugar-less scones. These are the questions that plague biscuit makers everywhere, and they are the questions that I have set out, over the past 13 months, to answer once and for all. Super-Flaky Buttermilk Biscuits. For the past year, I've performed dozens of biscuit experiments. Let’s have a look at them one by one. 19 days ago, Yes yes yes! In the 19th century, with the Industrial Revolution the mass production of cakes, biscuits and jelly began. But does it? By Jack G. Goldsmith, PhD. get fabulous ginger biscuits at the end. ACS Reactions. When you get a lot of butter, you're kind of filling your biscuit with holes, which makes it unable to bear its own weight to rise very far. Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College, 3/4 cup brown sugar (caramelized sucrose), 2-1/4 cups all-purpose flour (contains gluten), 1 teaspoon baking soda (sodium bicarbonate, NaHCO, You'll get the best results if you use room temperature eggs and butter. If your taste is like mine, then (for 8 biscuits), use: But maybe you just like your biscuits to be as big as possible. Scones are a totally different bread. COOKIE CHEMISTRY Cookies make a great vehicle to study chemistry and the scientific method. Thank you!!! So, you definitely get flatter biscuits when you add more butter (incidentally, the same is true with cookies... if your cookies are running all over the pan when they bake, just reduce the amount of butter/shortening and they'll hold their shape much better). In my quest to find the perfect sugar cookie for decorating, I have learned a lot about how individual cookie ingredients behave in a recipe. :-), Answer Yes, you can certainly add a little flour to make the dough easier to handle. If the cookies aren't devoured immediately, the chemistry doesn't end with baking. Both turned out pretty nicely: fluffy, flaky, and crispy on the thin outer crust. Werner’s theory. Conclusion: It's OK to use baking powder with buttermilk, but it's not OK to use baking soda with regular milk (at least according to this article). I cooked both batches on the same cookie sheet at 425 F, so baking conditions were identical. I use it whenever at all possible including for scones, cakes, and pancakes. About 1 tablespoon of baking powder per 2 cups of flour seems to be about the right amount, but even halving or doubling this amount should not ruin your biscuits. HOWEVER, I had one issue that didn't work well for me. Make sure you flour the cutter before each cut. on Introduction, Baking Soda needs an acid (like buttermilk), Baking Powder is Baking Soda with the acid already mixed in (so you don't need buttermilk). Buttermilk isn't blow-everyone-away better, but it might be a little better. Almost everyone, if you ask them, will tell you that buttermilk makes better biscuits. Others call for very little liquid, so it's difficult to mix the dough without over-kneading it. Just mix them with a fork (or anything else handy). Question See if that helps. Just use a pastry cutter to blend flour, baking powder, and a dash of salt with butter. You're not going to absolutely ruin the biscuits by "overworking" them. Usually its in the ballpark of 1/3 or 1/2 cup per 2 cups of flour, which is about half the amount of fat per flour that you put into a pie crust. Squishing the fat around with a fork until it's a bunch of little pieces coated in flour. Follow this classic chocolate chip cookie recipe and learn about the ingredients and the reactions that occur throughout the mixing and baking process. But to see if this is really necessary, I made three batches: You can definitely tell after 15 kneads or so that the dough is changing. Buttermilk isn't a straight swap for milk. Who knew. Yes, it's more exact to measure the actual mass (or weight) of your ingredients than it is to measure volume, but this experiment shows that huge variations in the amount of flour per liquid can still result in good biscuits. How can over to the soft spongy dough in the middle and away from the crumbs? Look here! To find out, I made five batches of biscuits that were identical except for the amount of milk used. There's only one way to find out: experimenting. This picture, taken right after the biscuits had finished baking, shows the same thing: Both taste testers (my wife and I) thought that batches 1 and 2 (with only a tiny amount of baking powder) were noticeably denser and moister than the others. The biscuits were subjected to … Still others swear by cream cheese. What’s the reaction? This experiment also (mostly) debunks the theory that you have to make your biscuits by using a scale rather than using cups and teaspoons. 4 months ago. In a humid environment, cookies can absorb water vapor, making them soft. The pan has two representative biscuits from each batch. Would taste-testers be able to tell the difference? Chemistry Class 12 Chapter 9 - Coordination Compounds. Individual chapters focus on the science of breads, pastry, biscuits, wafers and cakes. The pan has three representative biscuits from each batch. The consistency of the dough may vary depending on the fat used as different fats have different water contents. Batch 2: 3/4 cup of milk (3:8 ratio) Batch 3: 1 cup of milk (1:2 ratio) Batch 4: 1-1/4 cups of milk (5:8 ratio) Batch 5: 1-1/2 cups of milk (3:4 ratio) I then took a time-lapse video of the biscuits as they baked. To solve the milk vs buttermilk question, I decided to make two giant batches for a bunch of guests. There are many flavors of chocolate but Nabisco uses the formula of (H8N4C7O2) Which combines eight hydrogen atoms, four nitrogen atoms, seven carbon atoms and two oxygen atoms for delicious chocolate ready for consumption. I couldn't... not in taste, texture, or appearance, even on the bottom of the biscuit. What about the dissenter, who liked the butter biscuits better? If so, use more fat. The small variation in flour amount you'll get by measuring flour by volume will not ruin your liquid to flour ratio enough to ruin your biscuits. I recommend reading Harold McGee's On Food and Cooking for a better understanding of the chemistry involved in cooking and baking. Biscuits just pair naturally with traditional Southern fare like fried chicken, biscuits and gravy, and homemade jam. This combo makes a much more tender dough. on Step 14. Last week I made a batch of biscuits (yes, I enjoy cooking almost as much as chemistry). It all turns out to be crumbly biscuits. 5 years ago One of four voted for the buttermilk biscuit (because of "better taste"), One of four voted for the milk biscuit (because, "the other one has better taste, but this one has better texture"). 5 years ago As for taste and texture, my wife and I noticed two things: Kneading somewhere around 10x is probably ideal, but I seriously doubt anyone would complain if you kneaded 5x or 45x. One was 80% sure, and the last (a smart alec) was 64% sure. But margarine is usually several times cheaper than butter, and some argue that it's healthier. To find out what difference it makes, I made two batches: Three of four people liked the thick-cut biscuits better. Help? If the air is very dry, moisture from the cookies escapes, making them hard. The dough that was kneaded 15x and 45x was more "structurally sound" (like the biscuits we've seen before with less butter or milk). Traditionally, you use a round biscuit cutter. Share it with us! This helps the ingredients mix into the recipe more evenly and means your cookie dough will be. on Step 14. Chemistry and Food Sources, How to Substitute for Baking Powder and Baking Soda, 10 Examples of Mixtures (Heterogeneous and Homogeneous). Heat breaks the sucrose into the simple sugars glucose and fructose, giving each cookie a shiny, light brown crust. Many biscuit recipes caution against over-working the dough. And congrats to Solobo for the perfect experiment. Chemistry's Role The two main components of an Oreo is cocoa or chocolate, and the white cream on the inside of it. So how do you make the best, flakiest, most optimal biscuit ever? If the ingredients are high quality, measured carefully, and mixed as they should be, chemical magic happens in the oven to make great cookies. I learned a lot! Have you considered tweaking a recipe to use powdered buttermilk? Buttermilk doesn't seem to make a difference. I've tried to be as scientific as possible by: In this instructable, I will show the results of these experiments and my results for the "ultimate" biscuit recipe. The idea is that too much kneading will make the biscuits tough, hard, and nasty. Reply I rarely have buttermilk on hand and don't like the "add vinegar to milk" solutions and don't want to buy a carton to have it spoil because I only needed a little. Some biscuits, like drop biscuits, call for a lot of liquid, so the dough is super sticky and you have to "drop" lumps of it onto the pan. 1 year ago. Judging by appearance, I could not tell the shortening biscuits apart from the butter biscuits, but the cream cheese biscuits were a little cakier and less flaky looking. Some people swear by the baking mat, while some swear by the bare cookie sheet. on Introduction, Hi, I made biscuits using your recipe (your final preferred method), and, after many, many different attempts over the last few years, your biscuits came out better than any I've made before. You can see this well in the picture of the final biscuits as well: Surprisingly, all of the biscuits were extremely good. Again, the 1:2 liquid:flour ratio was about the easiest dough to handle. This video from the Royal Society of Chemistry (RSC), aimed at primary teachers, demonstrates an experiment which may be used when learning about solids. There are several chemical and physical changes which contribute to the colouring of the biscuit surface. Or maybe you're curious about some tests I haven't done yet, like: If that's the case, then check out my blog, where I've posted more installments of my continued quest for the "perfect" biscuit (as well as info on my novels, short stories, other food experiments, and book reviews). Four of eight people could tell no difference in taste between the shortening and butter biscuits. The very dry biscuits were really good, as were the very wet "drop" biscuits. Caramelisation is a non-enzymatic browning reaction, which is caused by the breakdown of sugars at high temperatures. Isn't chemistry fun? A ratio of 1/2 cup of butter to 2 cups of flour (1:4) seems to work pretty well. I did not tell my guests what the difference in the batches was until everyone had told me their opinion. It was slightly sticky, so you could save some mess by going with a 3:8 liquid:flour ratio. If so, up the baking powder, decrease the liquid and butter content, and knead them a bit more. BTW, I put my cut/out biscuits in my Lodge cast iron skillet in lieu of a baking sheet to bake them. I would think if it works, might be great for camping. I put three biscuits on a baking mat and 3 on a bare cookie sheet and baked at 425 F. Can you tell a difference? Answer This could lead to weak cookies or to cookies that fall flat when they come out of the oven. Also, be sure your biscuits touch each other in the pan, so the steam coming out of the edges can help their neighbor to rise. Heating sodium bicarbonate causes it to decompose into water and carbon dioxide: Carbon dioxide gas and water vapor form the bubbles which make cookies rise. Is it better to bake for a short time at a high temperature, or for a long time at a low temperature? I've read recipes that insist you only stir 15x after adding the milk and others that say you should knead only 5-10x. I then took a time-lapse video of the biscuits as they baked. A big variation in biscuit recipes is the amount of liquid (milk, water, buttermilk) that the recipe calls for. It causes the mixture to rise because it does this when it’s heated: 2NaHCO 3 –> CO 2 + H 2 O + Na 2 CO 3 What is best? Nope Scones use baking powder. But biscuits like those we eat today in the U.S. are fairly modern culinary creations. Fold the dough in half. In previous cookie science experiments, I examined how the wheat protein gluten (something that my friend couldn’t eat) affected how cookies look and taste. As you can see in the pictures, the dough that was kneaded only 5x didn't rise quite as much as the other biscuits. This is usually wheat but is sometimes oat, barley, rye, or rice. Cookies were rich in magnesium (576.54–735.06 mg/100 g) with favorable Na/K ratio (<1.0). Two of five thought the milk biscuits had a little better taste. But how does that affect the final product? 1 cup of liquid (milk, buttermilk, or water), 1/2 cup of fat (butter, stick margarine, or shortening), working the dough even less (COMPLETE: see, cutting the butter in vs. melting it and pouring it in, sour cream (apparently it's also a thing). The humidity of the surroundings affects cookies after they have cooled. When the industries face a problem of shortage of raw materials supply the cost of the biscuits will increase and hence be the reason for change in cost price structure. I didn't tell anyone what the difference between biscuits was until after they'd made their choice. A demonstrator uses biscuits to show children that some solids are made of tiny pieces and can be poured. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. When you take the cookies out of the oven, the hot water gases in the cookie contract. There's a little bit of debate on how thick you should roll out your biscuits before you make them. The only difference between the batches was the amount of baking powder used: I then took a time-lapse video of the biscuits as they baked. Each batch uses two cups of flour and normally makes 8 biscuits, but I only cooked two biscuits from each batch so that I could make sure the baking conditions were exactly the same for all of the biscuits. Number 2 contains 50w% flour, 33w% sugar and 17% butter. I'm kind of assuming that I might need a little bit more flour added? The gluten in the flour forms a polymer mesh that works with the albumin protein from the egg white and the emulsifier lecithin from the egg yolk to form the dough and support the bubbles. Welcome to the School of Chemistry at Trinity College Dublin, a vibrant place to work and study, with staff who carry out cutting-edge research and strive to deliver a world-class education to our diverse community of undergraduate and postgraduate students. Food Chemistry in the High School Classroom Cook up some chemistry learning. This can be the hardest step. Yes, your dough is a bit too wet. I've varied the shotlrtening from 1 tblspn per cup of flour to 3 tblspns per cup and I've varied baking powder from 1 tspn per cup to 3 tspns per cup, and I have tried varying buttermilk from barely enough to form a batter to so much I could barely get the batter to be able to knead it. The price of the biscuits vary according to the availability of raw materials and internal factors or environment. I made a single batch of six biscuits. Well, that depends on your taste. We've already seen what the amount of fat does to a biscuit, but what does the type of fat do? Cream cheese is a decent (but inferior) alternative if you're worried about fat content (cream cheese has about half as many calories from fat as butter or shortening). It turns out that it's not. After preparing the dough and rolling it out/patting it out, I used my biscuit cutter (rather than a knife) and I didn't get a nice clean "cut"......I had a somewhat messy, wet dough to contend with. To find out, I made two batches of biscuits that were identical except for the type of fat used. The science of biscuit baking | Recipes | rapidcityjournal.com And when you put both cream of tartar and baking soda, you have made; baking powder!Chemistry SHOULD be fun! I understand lard makes a flakey biscuit. What’s the chemistry connection? It’s actually more of a science… chemistry really. Thanks for reading! Butter or shortening? I often mix up per the recipe and add a generous amount of flour on the counter to adjust as I roll out the dough. I’ll experiment a bit more! I made a single batch of biscuits and baked two biscuits at 425 F and two biscuits at 350 F. It took a little longer to finish at 350 F (20 minutes vs 15 minutes), but the resulting biscuits were almost indistinguishable. After the moisture has been mainly evaporated from the dough pieces, the temperature of the surface rises quickly and the colour will change from around 150°C. I asked how sure everybody was of the difference? 18 days ago. Tastier? Making good biscuits is easy. I'm a camper & frequently make biscuits in a Dutch oven; your experiments will help create a recipe that is much more "portable" than my usual recipe! But what difference does the fat make? Reply Two of eight people thought the milk biscuits were maybe a little "saltier", but couldn't decide which they liked better. Coordination compounds. Department of Chemistry, Pima Community College, Tucson, AZ A National Chemistry Week trip to Tennesse resulted in my staying at the home of a colleague and being treated to some wonderful home-made baking powder biscuits. Repeat about 10 times. I then took a time-lapse video of the biscuits as they baked. None of these biscuits were bad, but again, the middle option seems to be the best choice. Oven temperature is 425 F. In this first experiment, I didn't have any store-bought buttermilk handy, so I made my own: Inconclusive. Three of five thought the water biscuits were fluffier and better overall. You can substitute baking powder for baking soda (since you're just making double-sure there's enough acid for the reaction), but you can't substitute baking soda for baking powder (since that acid needs to come from somewhere). Another big variable in biscuit recipes is the amount of fat (butter, shortening, etc.) My short stories have been appea…, changing only one thing at a time (the amount of fat or the type of liquid, for example), testing multiple types of biscuits on the same day (so that taste testers can say "biscuit A is better than biscuit B" rather than having to say, "Yeah, I think these taste better than the ones you made last week!"). Are biscuits fluffier with more or less fat? After making several batches of cookies we could conclude that the ratio of just these three ingredients has a major impact on how your shortbread cookie turns out. There isn’t enough butter to make a … If I remember correctly, scones contain yeast. Based on the chemistry, I think this is where you will see a greater difference making biscuits with or without buttermilk. Reply One of the principle ingredients for biscuits is wheat flour. But first a little about technique: how do you make biscuits in the first place? Biscuits, cookies, and crackers have a cereal base of at least 60%. Each batch uses two cups of flour and normally makes 8 biscuits, but I only cooked two biscuits from each batch so that I could make sure the baking conditions were exactly the same for all of the biscuits. Increasing the amount of butter definitely makes the biscuit "taste" softer, more crumbly, and more flaky. Rising doesn't just make cookies taller. Nomenclature of Coordination Compounds. Reply Biscuits were significantly (p < .05) different in their nutrient composition, with the crude protein, crude fiber, ash contents, and dietary fiber content increasing as the PPF level increased. I did this experiment many times. I love the information you provided pertaining to you biscuits! Oven temperature is 425 F. The video shows that you get a lot more rising for drier biscuits. One of eight people thought the butter biscuits tasted slightly saltier and slightly better. I'm trying to get a biscuit whose center is soft, fluffy and for want of an exact description, spongy.....no crumbs!! Some people think the amount of baking powder used is very specific and important, while others seem to think it's almost unnecessary. Bath Oliver biscuits were invented by William Oliver in the mid 18th century. The process of creaming is, simply put, just mixing butter and sugar together. The chemical changes that occurred during baking help the cookie keep its shape. The basic characteristic that separates a biscuit, cookie, or cracker from other baked products, such as bread or cake, is a moisture content below 5%. By the time you get to 45 kneads, you're starting to get tired, and the dough is resisting you. Or are some of the mysterious steps in these recipes as arbitrary and nonsensical as cutting off both ends of the ham? For flavor, you can do half lard, half butter. Two of eight people thought the shortening biscuits tasted better than the butter biscuits. Others demand shortening. The aim of this work was to produce biscuits from wheat flour substituted with different amounts of wheat sprout powder (2.5–7.5%). Here, I show why different temperatures of butter matter to a recipe. Put the biscuits on a baking sheet and stick them in the oven. You can use baking soda if you add an acid like cream of tartar, vinegar or even a splash of citrus or citrus rind. Sometimes I used "real" store-bought buttermilk. I say mostly debunks because, theoretically, some other ratio could be super crucial to the science of biscuit making. The Difference Between Baking Soda and Baking Powder, How Baking Soda Works to Make Baked Goods Rise, What Is Gluten? Squish it. Reply The Science of Bakery Products is an interesting and easy to read book, aimed at anyone with an interest in everyday chemistry. This is why undercooked cookies (or other baked goods) fall in the center. Hmm, I'm really not sure. Using two table knives (or scissors) to cut the fat up until it's a bunch of little pieces coated in flour. This is usually wheat but is sometimes oat, barley, rye, or rice. It gets harder to fold, stiffer, more "bready". To find out, I made three batches of biscuits that were identical except for the amount of fat used (in this case, butter). If you can, cut round biscuits and then put them in a cast iron skillet touching edges and then in the oven. ), Reply You could try using bread flour (which has more gluten and should end up chewier) or maybe removing from the oven earlier (I don't overcooking is causing the crumbliness but that's all I can think of). Since 2015, the School has been the proud holder of a Bronze Athena SWAN Award So what difference does baking powder really make? That's why some recipes call for both.In addition, I think I read somewhere that one rises quicker than the other, which is why some recipes might call for both, so you get a rise right away and another later on. The Science of Baking Infographic Check out this break down of baking, one ingredient at a time. The blend should be light and crumbly, not heavy and pasty, or dry and dusty. There are three processes which contribute to the browning of the biscuits. The same chemical reaction can also be used to make cinder toffee or honeycomb. It turns out that for biscuits, it doesn't make a difference. I love writing, leather working, cooking, and playing board games. Modern Cakes and Biscuits. My favorite was the middle batch, with 1.5 teaspoons of baking powder, but my wife thought this one was a little too dense. relevant chemistry can be to explaining things that are important to you in everyday life.
