Yes, but only if you understand the weird science of starch. Cornstarch is a thickening ninja. Cornmeal is a textural bricklayer. They work in different universes.
Imagine making cornbread with cornstarch. You’d get a dense, rubbery pancake. No crunch. No soul. Your ancestors would cry—silently, like a ghost.
Now imagine cornmeal in a sauce. You’d get a gritty, sad mess. Like eating sand. So no, you can’t just swap them 1:1. But you can get creative.
The Great Frying Escape
Here’s a quirky fact: cornstarch makes things crazy crispy. Cornmeal makes things crunchy but heavy. If you’re frying fish, cornmeal gives you a golden coat. Cornstarch gives you a shatteringly light shell.
So for tempura? Use cornstarch. For Southern-style catfish? Use cornmeal. But if you mix them? You get magic. A 50/50 blend gives you a crust that’s both crunchy and fluffy. It’s the superhero of fried foods.
