tb. corn starch

Cornstarch, also known as maize starch or corn flour in some regions, is a fine white powder derived from the endosperm of corn (maize) kernels. It is produced by wet-milling corn to separate the starch granules from other kernel components, then drying the isolated starch. Cornstarch is virtually tasteless and odorless, with a silky texture and high thickening power due to its pure starch composition (approximately 99.5% starch). It remains a neutral ingredient that does not contribute flavor, making it ideal for applications where starch functionality is desired without flavor interference.

Unlike cornmeal or corn flour (which retain bran and germ), cornstarch is refined to pure starch and gelatinizes at relatively low temperatures (around 65-75°C), creating a clear, glossy thickened liquid when dispersed in water and heated. This property distinguishes it from wheat starch and other starches.

Cornstarch serves as a versatile thickening agent in both sweet and savory cooking. It is commonly used to thicken sauces, gravies, puddings, and custards, and is essential in many Asian stir-fries and braised dishes where a glossy sauce is desired. In baking, cornstarch is blended with wheat flour to produce tender cakes and pastries by reducing gluten development. It also functions as a dusting powder for dough and surfaces to prevent sticking.

Cornstarch is widely employed in Asian cuisines (particularly Chinese) for velveting meats and creating silky sauces. It appears in desserts ranging from panna cotta to pie fillings, and serves as a component in coating mixtures for fried foods. The ingredient's neutral flavor profile and ability to produce transparent, glossy results make it distinct from flour-based thickeners.
