Potato starch

Used in 2 recipes on RecipeWiki.

Potato starch is a fine white powder made from the starch in potatoes. It thickens sauces with a glossy finish and gives fried coatings a crisp, delicate shell, but it should be mixed with cold liquid before it reaches a hot pan or it will clump. Use it when a sauce needs clarity rather than the opaque finish of flour. It is also useful in gluten-free baking, where a small amount lightens a mixture of heavier flours.
