    What is Kuzuyu?

    What is kuzu powder (kuzuko)?

    Kuzu powder, or kuzuko, is a white starch powder obtained from the kudzu root. In its purest form, it consists of 100% kudzu starch powder, often labeled as “Honkudzu.” This authentic kuzu powder is highly regarded for its medicinal properties and culinary uses.

    Definition of Kuzuyu

    Kuzuyu is a cozy, thick drink created by blending kuzu powder (kuzuko) with hot water. People love it for its soothing warmth. While “Honkudzu” is the fancy version, many store-bought kuzuyu options mix kudzu with potato starch. Homemade kuzuyu, made with potato starch, provides the same comforting feeling. Whether you pick the real deal “Honkudzu” or an easier choice, kuzuyu holds a special place in Japanese culture, particularly during chilly times of the year.

    Kuzuyu itself has a mild flavor, but seasoning plays a key role. Adding sugar makes it sweeter, resembling Japanese sweets, and it’s useful when you have a small appetite or can’t eat much. Sometimes, ingredients like ginger, known for warming the body, are cooked with it to enhance its warming effect. You can also mix in citrus juice for a refreshing twist or even add ice for a different texture. The beauty of Kuzuyu lies in its versatility, allowing you to savor various flavors and styles through different preparations.
