What is corn flour?

Corn flour is finely ground cornmeal. Corn flour comes from dried corn that is slaked, or soaked in lime water. Some of its most popular uses are for breading or combining with other flours for baked goods.

After the corn is slaked, it is washed and the hulls are removed. This damp corn is then ground into a fine powder. This flour is made from white, yellow or blue corn.

Corn flour is milled from the whole corn kernel, while cornstarch is just made from the kernel's endosperm. A certain kind of corn flour, called masa harina, is the ingredient required for making corn tortillas.
