What is Potato Starch?

Potato starch is a starch powder, much like corn starch, that is made from crushed potatoes. This starch is what makes raw potatoes react and change colors when left exposed to the air. Potato starch is often used as a thickener for hearty soups and stews. Most people do not keep this simple thickener on hand and can be thrown off when they are working on a recipe and it pops up.

Coconut flour makes a suitable substitution for potato starch in recipes. This flour is a great option for those looking to make gluten-free or low carb recipes, and can be used in both soups, stews and homemade bread options in a 0.5 to 1 ratio with potato starch. If more than 1/4 cup coconut flour is needed to replace potato starch in a recipe, you may need to add a bit more liquid to the recipe, as coconut flour is more absorbent than potato starch.
