Cornstarch (potato starch works similarly)

Description

Cornstarch is a fine, white, silky powder with an almost neutral, light flavor that, when cooked, gives a transparent, glossy gelatinous consistency; potato starch works very similarly, although it may produce a slightly more opaque thickening. Starch is mainly composed of carbohydrates, contains minimal amounts of protein and fat, and is relatively high in calories, but is naturally gluten-free and easily digestible, making it a useful alternative for those with gluten intolerance; however, it should be used in moderation due to its high glycemic index. In the kitchen, it primarily serves as an effective thickener for sauces, soups, creams, and puddings, for clarifying and glazing, as well as an additive to bread and cakes for a more delicate texture and for breading when frying for a crispy crust. It should be stored in a tightly sealed container in a cool, dry, and dark place, away from moisture and odors, and used within a few months after opening to avoid clumping and rancidity.
