Corn flour is actually a powder ground from mature corn, so corn flour is actually what we call corn flour in daily life.

Anyone who has seen corn flour knows that it is non-sticky if it is raw, so it can't replace flour if you want to steam steamed bread. If you want to steam steamed bread with corn flour, you can mix it according to the ratio of flour to corn flour of 3:1. If you want to fry something, you can use corn flour instead of flour.

However, when we use corn flour instead of flour, one problem we need to think about is that flour contains essential amino acids for human body, but corn flour does not, so we need to consider this problem when we want to replace it.
