But First, What is Cream of Tartar?**bold text**
Cream of tartar, also known as potassium bitartrate or potassium hydrogen tartrate, is a winemaking by product. It is formed from the sediment left over in barrels after the winemaking process; once formed, it is scraped off of the sides of the barrels and then cleaned and ground to form cream of tartar. In cooking, it is known as cream of tartar.
Cooking With Cream of Tartar
The best use case for cream of tartar is to stabilize egg whites for meringues. Cream of tartar helps eggs maintain their texture when whipped into stiff peaks and also increases their tolerance to heat, which is pretty helpful for baking. This allows eggs to brown & hold their shape.
The Science: Cream of Tartar & Egg Whites
When you beat egg whites, proteins in the whites unfold from their natural shape and become tangled with each other. At the same time, you are beating air into the whites, forming small bubbles. The protein molecules become attached to each other through chemical and electrical bonds that reinforce the skin of the air bubbles. Over time, these bonds can pull the proteins closer together, forcing out the water trapped in the surface of the bubbles. Eventually, the proteins pull themselves together so strongly that compact, grainy protein lumps form and the liquid pools in the bottom of the bowl.
This is where the cream of tartar comes in. It helps prevent the formation of chemical bonds between protein molecules.
