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.
Shortbread is a delicious cookie. Buttery and rich, it’s a treat whose decadence belies its simplicity. A basic shortbread contains only butter, sugar, and flour, but these ingredients create a crumbly dough that can be difficult to work with. To give our dough more structure, we can add a touch of water to the flour to develop gluten before it’s combined with the butter. In this post, we’ll explore how the extra water affects the cookie, from mixing bowl to oven into our mouths.
In the introduction to gluten, we described gluten as a protein that contributes to the structure and texture of baked goods. The ideal amount of gluten depends on what we’re making, and there are several ways we can influence the extent of gluten development. We can first choose a flour based on its protein content,Continue reading “Gluten in the Kitchen”
