Want to make polenta but you only have cornstarch? Stop right there. Polenta needs cornmeal’s grit to be creamy. Cornstarch will give you a glue-like paste. That’s not dinner—that’s a craft project.
But if you’re desperate, you can mimic cornmeal’s texture. Toast regular flour with a tiny bit of cornstarch and a pinch of turmeric. It won’t fool a chef, but it might save your taco Tuesday.

In baking, cornmeal adds structure and a subtle crunch. Cornstarch adds tenderness. They’re opposites. A pancake mix with cornstarch instead of cornmeal will be soft and cakey, not rustic.
Here’s a funny detail: professional bakers sometimes use cornstarch to dust their pans. They never use cornmeal for that—it would burn into a black crust. Cornstarch burns too, but it turns into a weird caramel-like film. It’s gross. Use flour instead.
