Cornstarch is pure starch from corn kernels. It’s a fine, white powder that feels like silk between your fingers.
Its one job is to thicken things. You use it in gravy, pudding, and stir-fry sauces.
Fun fact: Cornstarch is a thief of moisture. It soaks up liquid like a tiny sponge, turning runny soup into glossy magic.
Baking powder, on the other hand, is a total liar. Well, it’s a chemical liar—and we love it for that.
