Cornmeal

Cornmeal's hub page centers on its coarser, grittier grind (138g per cup, one of the heavier grain products on this site) and the genuine confusion around its name — cornmeal and corn flour aren't the same product despite the overlap, with corn flour ground much finer, closer to wheat flour's texture.

Grind size is the fact most worth connecting here: coarse cornmeal (often labeled polenta) needs a longer cook time to soften in a wet application, while fine cornmeal cooks faster and blends more smoothly into a batter — a recipe's specified grind genuinely matters, not just a stylistic preference.

Cornmeal is naturally gluten-free, since corn contains none, and this site's guidance notes checking for a certified gluten-free label if cross-contamination during processing is a specific concern, the same caveat that applies to oats.

Cornmeal is milled at several different grinds — fine, medium, and coarse — and a recipe written for one grind can turn out gritty or unexpectedly smooth if a different grind is substituted, since that texture is often the entire point in a dish like cornbread or polenta, meant to remain perceptible rather than dissolve smoothly the way a wheat flour would.

Yellow and white cornmeal come from different corn varieties and taste nearly identical, with the color difference coming from the corn itself rather than any processing difference — a distinction that matters more regionally (white cornmeal is traditional in some Southern US cornbread recipes) than for flavor.

Masa harina, used for tortillas and tamales, is a distinct product from standard cornmeal despite both being corn-based — masa harina is made from corn treated with an alkaline solution (nixtamalization) before grinding, a process that changes both flavor and how the corn behaves when made into dough, unlike plain ground cornmeal.

Cornmeal and the broader use of corn as a food staple trace directly back to Indigenous agricultural practices in the Americas, where corn (maize) was one of the most significant domesticated crops — its later adoption into Southern US cooking specifically reflects a much older Indigenous agricultural and culinary foundation.

Grits, a Southern US staple, are made from a specific type of coarsely ground corn (often hominy, corn treated with an alkaline solution) — related to cornmeal but processed and prepared differently, typically simmered into a soft, creamy porridge rather than baked.

Hominy, corn kernels treated with an alkaline solution and dried whole rather than ground, is the starting point for both grits and masa harina, connecting several corn-based staples to a shared processing origin.

Anasazi corn and other heirloom varieties grown by Southwestern Indigenous communities represent a considerably older and more genetically diverse corn tradition than the standardized commercial varieties used for most modern cornmeal.
