Kudzu has been used as food and medicine for centuries, making it an essential part of Japanese life. Let’s dive into what kudzu is, its origins, health benefits, and how it’s used today. You’ll also discover why kudzu starch (kudzu powder) is a prized ingredient in Japanese cuisine.
What Is Kudzu?
The Origin of Kudzu and Its History in Japan
Kudzu originates from East Asia, where it has been cultivated and used for thousands of years. In Japan, its use dates back to ancient times, with mentions in records from the Nara Period (710–794). By the Heian Period (794–1185), kudzu had become a luxury ingredient appreciated by the nobility.
Characteristics and Growth Environment
Kudzu is a perennial vine in the pea family, known for its rapid growth and resilience. It thrives in mountainous or barren areas and blooms with beautiful purple flowers from summer to autumn. Its roots are rich in starch, which is extracted to produce kudzu powder.
How Kudzu Powder Is Made
Kudzu powder is made by crushing the plant’s roots, repeatedly rinsing them with water, and removing impurities. This labor-intensive process results in a pure, fine starch prized for its smooth texture and transparent finish, making it ideal for cooking and desserts.
