Cornstarch is a fine, powdery starch that is made out of corn. The cornstarch is actually made from the endosperm of the corn, which makes up most of the kernels that we eat when enjoying popcorn or corn on the cob. Cornstarch, also sometimes called cornflour, is produced by grinding, washing and drying the endosperm of the corn until it reaches that fine, powdery state. Cornstarch is gluten free.
