FAQ

Frequently asked questions.

How does cornstarch thicken food?▾
When heated in a liquid, cornstarch granules absorb water and swell significantly, causing the liquid to thicken. This process, known as gelatinization, is crucial to its effectiveness as a culinary thickener for gravies and custards.
Can cornstarch be used in baking?▾
Yes, a small amount of cornstarch is sometimes added to flour in baking, especially for cakes, to create a finer, more tender crumb. It helps to slightly reduce the overall protein content of the flour mixture.
Would Nonna recognize cornstarch?▾
Yes, Nonna would definitely recognize cornstarch. It's a traditional kitchen staple that has been used for generations as a thickening agent in many classic recipes, from custards and puddings to fruit fillings and savory gravies.
