How to measure cornmeal

Cornmeal is coarse and heavy, so it weighs noticeably more per cup than wheat flour.

Because a cup measures volume rather than weight, the most reliable way to measure cornmeal is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for cornmeal

1 cup cornmeal = 1 cup polenta (coarse) or corn grits (Salted Plains)
Same ingredient at different grinds. Coarse polenta gives more crunch in cornbread; for a finer crumb, soak briefly in the recipe's liquid first.
1 cup cornmeal = 1 cup corn flour (for a finer crumb) (Bake It With Love)
Corn flour is finely ground cornmeal; result is softer and more cake-like, with less of cornmeal's signature grit.

Cornmeal conversions: FAQ

Why doesn't a cup of cornmeal weigh the same as a cup of water?

A cup measures volume, not weight. Cornmeal is less dense than water (138 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
