Kuzu is a special ingredient from the root of Pueraria lobata, regarded by many as one of the largest roots in the world. This powerful thickener is commonly used in Asian cuisine to give body to soups and sauces. Unlike other thickeners, it dissolves in cold, making it a versatile and easy-to-use option. Simply dissolve 1 to 2 tablespoons in a cup of cold liquid and add it to the cooking of soups, creams, or puddings. As it cooks over low heat, kuzu transforms into a translucent gel that gives dishes a pleasant texture.
