Potato starch and potato flour are two pantry staples that are often used in gluten-free cooking and baking. While they may seem similar, they have different properties that can greatly affect the outcome of your recipe.
For example, potato starch is often used to thicken sauces and gravies, while potato flour is used to add structure to baked goods. In this article, we’ll take a closer look at the differences between potato starch and potato flour, how to cook with them, and their health benefits.
What is Potato Starch?
Potato starch is a white, fine powder that is extracted from potatoes. It is made by peeling the potatoes, washing them, and then grinding them into a slurry. The slurry is then washed to remove the starch, which is then dried and milled into a fine powder.
Properties of Potato Starch:
- Texture: Potato starch is a fine, powdery substance that dissolves easily in water.
- Taste: Potato starch is flavorless, which makes it a good thickener for dishes where you don’t want to alter the flavor.
- Color: Potato starch is white, which makes it ideal for use in dishes where you don’t want to change the color.
What is Potato Flour?
Potato flour, on the other hand, is made from whole potatoes that are cooked, dried, and then ground into a fine powder. Unlike potato starch, potato flour contains the entire potato, including the skin and fiber.
Properties of Potato Flour:
- Texture: Potato flour has a slightly grainy texture and is denser than potato starch.
- Taste: Potato flour has a mild potato flavor that can add a subtle taste to baked goods.
- Color: Potato flour has a slightly off-white color due to the inclusion of potato skins.
