Cornmeal is made from dried and ground corn kernels, which can be either fine, medium, or coarse in texture. The coarser the grind, the more texture and flavor it'll add to your dishes. Think of it like choosing the perfect coffee grind - you want the right balance to get the best results.
Now, let's talk about cornstarch, the other corn product that's often confused with cornmeal. Cornstarch is a fine, powdery substance that's extracted from the endosperm of the corn kernel. It's a popular thickening agent, often used in sauces, soups, and marinades to add a silky smooth texture.
