A solid carbohydrate that is granular in form and naturally present in many plants such as grains (wheat or rice), pulses (corn), tubers (potatoes), and numerous other plant species.
A small, narrow potato (generally 2 to 4 inches in length) that is actually a very young tuber. The potato has a finger-like appearance and a firm texture that varies from moist to dry, with a flavor that ranges from a mildly sweet to rich and nutty.
A powdery substance obtained from wheat kernels. It is very useful as a thickener, but it doesn't have as much thickening power as cornstarch, which requires only half as much to achieve that same level of thickening.
A flour-like, gluten free substance produced only from the starch of the potato. It is a very fine powder and can be used with other types of flour for baking.
