Corn meal ground into a powder using a food processor can be used as a substitute for corn flour. If a recipe calls for corn flour to be used as breading, regular flour can be used as a substitute.
Corn flour is made by grinding whole corn kernels into a fine powder, and it is used primarily in baking and breading. Corn meal is also made from ground corn kernels but has a coarser texture than corn flour.
When baking, substituting corn flour for wheat flour results in a heavier bread. Corn flour contains less gluten than wheat flour, and corn meal does not contain any gluten.
