Kuzuyu (hot kudzu drink)
Kuzuyu is what Japanese mothers make when someone has a chill or an upset stomach, and what many people sip on a frosty winter evening, especially in Nara, whose Yoshino mountains have produced the finest hon-kuzu starch for centuries. Kudzu root starch is stirred into water with a little sugar and cooked until the milky liquid suddenly turns clear, glossy and gently thick, somewhere between a hot drink and a soft pudding you drink from the cup. Grated ginger warms it; some families add a spoon of matcha or a squeeze of yuzu. It tastes clean, mildly sweet and comforting, and it is traditionally given to people recovering from colds. The mistake almost everyone makes once is sprinkling kudzu into hot water, where it forms rubbery lumps at once. Always crush it and dissolve it completely in cold water first, then heat it while stirring without stopping. It is ready when there are no white streaks left, the drink is translucent and it coats the back of a spoon. Chef's tip: real hon-kuzu comes in chalky lumps; crush them with the back of a spoon in the cold water and they dissolve in seconds.
