tbs. kudzu

Kudzu (Pueraria montana var. lobata) is a starchy thickening agent derived from the root of an invasive perennial vine native to East Asia, now widespread across the southeastern United States. The ingredient consists of finely ground kudzu root starch, which is off-white to pale cream in color with a fine, silky texture. It is nearly flavorless and odorless, dissolving readily in cool liquids before thickening under heat. In Japanese cuisine, it is known as kuzu and has been used traditionally for centuries as a culinary and medicinal ingredient.

Kudzu starch is primarily composed of polysaccharides and contains minimal protein or fat. It has a higher gel strength and clarity compared to cornstarch, producing transparent, glossy thickened liquids rather than opaque slurries.

Kudzu powder is used primarily as a thickening agent for soups, sauces, gravies, and desserts, offering superior clarity and a silky mouthfeel compared to cornstarch or flour. In Japanese cuisine, it appears in warabimochi (a traditional sweet jelly dessert), kuzu kiri (cut gelatinous noodles), and clear broths. In East Asian cooking, kudzu is valued for glossy coatings on stir-fried dishes and for creating delicate custards. In Western and contemporary fusion cooking, it serves as a gluten-free thickener. It must be mixed with cool liquid before adding to hot preparations to prevent clumping.

The ingredient also carries significance in traditional Chinese and Japanese medicine, where it is believed to have warming and digestive properties.
