One of the most important functions of eggs is to provide structure and determine texture. We saw this with breads, cakes, cookies, and muffins, with brownies, and also with meringue. But there’s one more category of baked good that depends on eggs: custards and creams. Eggs set and thicken crème brûlée, quiche, cheesecake, pastry cream, and crème anglaise. In this post, we’ll first review how an egg cooks, then explore how different ingredients and techniques affect this process to create smooth custards and creams.
In the last post, we covered eggs’ many roles in cakes, cookies, muffins, and breads. But eggs are even more versatile when we consider what they can do with air. Think about it: egg whites on their own are dense and chewy. But with air (and sugar), they become light, crisp, melt-in-your-mouth meringue cookies. Add a few more ingredients, and we can make macarons, pavlovas, cake frostings, soufflés, and sponge cakes. In this post, we’ll explore how meringue forms and how we adjust its texture for different bakes.
With our foundation of proteins, carbohydrates, and lipids, we’re now ready to explore more chemically complex ingredients. First up? Let’s start with eggs.
In the last post, we focused exclusively on flour and the role of its starch in baked goods. Today, we’ll explore how starch’s chemical properties make it useful in desserts such as buttercream, meringue, and custard. We’ll also consider how other ingredients affect starch in these recipes. Starch is a drier. As we discussed inContinue reading “Starch in the Kitchen: Stabilizers and Thickeners”
In the last post, we explored the roles of baking powder in muffins by taking it out of a recipe and then by adding in extra. Today, we’re going to continue experimenting with leaveners in muffins, but now we’re going to add baking soda into the mix. We discussed the differences between baking soda and baking powder in a previous post, but now we’ll see how these differences play out in a baked good.
Baking powder is used in such small amounts it’s often overlooked in ingredient lists. But this unassuming powder is crucial for volume and tenderness in baked goods such as muffins, biscuits, cookies, and cakes. In this experiment, we varied the amount of baking powder in muffins to see how the muffins would change in appearance, taste, and texture.
Baking soda and baking powder are used in all sorts of baked goods including cookies, cakes, and muffins. They can be used independently or in conjunction. And although they both contain the word “baking” and produce carbon dioxide to help leaven our bakes, there are differences that are crucial to understanding how they work in a recipe.
In the past few posts, we focused on sugar’s roles in baked goods and its interactions with other ingredients. But sugar is also crucial to candies like caramel, fudge, and fondant, for which careful control of sugar crystallization is paramount for texture. In this post, we’ll explore the chemistry of crystal formation in the candy making process.
Over the last few posts, we discussed the effects of sugar on cookie spread and texture. For this recipe, I played around with maple syrup, brown sugar, and granulated sugar. I also experimented with oven temperature. The result is these Maple Walnut Snapdoodles, one cookie dough that can be crunchy or chewy depending on the oven temperature. In addition to the recipe, I’ll share some of the test batches. We’ll talk about the changes I made, the results of each batch, and the science behind it all.
While the polarity of sugar and its attraction to water give it the many crucial properties we discussed in the last post, sugar also functions independently of water. Sugar provides volume, aeration, color, and flavor for our baked goods.
