Egg Foams in the Kitchen: Meringue

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.

Starch in the Kitchen: Stabilizers and Thickeners

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”

Sugar in the Kitchen: Special Applications

Over the last few posts, we discussed a lot of sugar’s roles in baked goods. It’s important for flavor, texture, structure, and color in cookies, cakes, and muffins. But sugar’s roles in baking extend further. Sugar is important in meringues as a stabilizer, in yeast breads as a source of energy for the microorganisms, and in fruit desserts to preserve the structure and texture of the fruit. In this post, we’ll explore sugar’s myriad roles in these sweets.

Proteins in the Kitchen

In the last post, we described proteins as strings of amino acid beads that we reshape when we bake. In this post, we’ll discuss how we manipulate some of the most important factors in protein shape such as water availability, acidity, and temperature, and we’ll explore the chemical effects of these changes.
