Measuring cornmeal
Coarse and fine grinds weigh differently; check your package if it lists grams.
These weights are for cornmeal (whole-grain, yellow). A different form, or a cup filled another way, weighs differently, so weigh it if the recipe gives grams.
The King Arthur Baking ingredient weight chart gives 138 g per cup. Grind size varies by brand. We use the USDA figure throughout.
