Is Cornstarch Just Corn Flour? The Truth Revealed!

The world of cooking ingredients can be confusing, especially when it comes to cornstarch and corn flour. These two ingredients often get mistaken for each other, but they are quite different in their composition and uses. In this blog post, we will delve into the world of cornstarch and corn flour, exploring their differences, similarities, and culinary applications.

What is Cornstarch?

Cornstarch is a fine, white powder made from the endosperm of corn kernels. It is a starch, which means it is a complex carbohydrate composed of glucose molecules. Cornstarch is commonly used as a thickening agent in cooking, adding body and texture to sauces, soups, and gravies. It is also used in baking to give baked goods a tender crumb.

What is Corn Flour?

Corn flour, also known as cornmeal, is a ground cornmeal made from the entire corn kernel, including the germ, endosperm, and bran. It is a coarse, yellow powder with a gritty texture. Corn flour is commonly used in baking, particularly in cornbread, muffins, and tortillas. It can also be used as a breading for fried foods.
