What is potato flour?
Potato flour is a flour which is produced from potatoes which have been cooked, dried, and then ground potatoes. It is commonly confused with, but is different than, potato starch flour which is made only from the starch of a potato. Potato flour is typically less dense and less white than potato starch. There are a number of uses for potato flour, ranging from Passover cooking to gluten-free baking. Large markets and health food stores may carry this type of flour, and it is also available by direct order through retailers who specialize in such foods.
