Potato Starch
Completely neutral and flavorless; creates a cleaner, more transparent thickened sauce than cornstarch, with a slightly silkier mouthfeel.
Lens analyzedPotato starch is a fine, pure white starch extracted from potatoes — used as a thickener for sauces and gravies and as a coating for frying, where it produces an especially light, crispy crust.
Where it comes from
Potatoes were domesticated in the Andean highlands of Peru and Bolivia and brought to Europe in the 16th century. European food processors quickly discovered that the starch could be extracted from potatoes and used as a thickening agent or processing aid, and industrial potato starch production was established in Germany and the Netherlands by the 19th century. In North America, potato starch is found in Kosher cooking (as a Passover-friendly thickener) and in East Asian cuisine, where it produces a distinctively airy crust in fried dishes.
Varieties — Standard potato starch is a single product; it differs from potato flour, which is made from cooked, dried, and ground potatoes and has a pronounced potato flavor.
Used in Jewish Passover cooking as a wheat-free thickener; common in Korean and Japanese cooking for coating fried chicken (dakgangjeong, karaage); widely used in Chinese stir-fry sauces.
In a modern kitchen — Potato starch thickens at a lower temperature than cornstarch and creates a very clear, slightly glossy sauce — use it for delicate sauces where you want maximum clarity.
Buying it
Look for pure potato starch — it should be a very fine, bright white, odorless powder. Distinguish it clearly from potato flour, which is tan and has a potato flavor and very different culinary properties. Available at Asian grocery stores, Jewish grocery stores, natural foods stores, and online.
Storing it
Store potato starch in an airtight container in a cool, dry pantry spot — moisture is what causes it to clump or take on a musty smell.
Keeps about 1 year in the pantry.
Out of potato starch? Good swaps
- Cornstarch — 1:1 ratio for thickening; more opaque result; slightly different texture in fried coatings
- Arrowroot starch — 1:1 ratio; equally clear and neutral; does not hold as well after reheating
