Masuda city’s other iconic local cuisine: Ayu Zoni (Japanese soup with ayu, the sweetfish). Takatsu River is known for its clear stream, which is a perfect habitat for the ayu. In Japan, having zoni on New Year’s Day has been a tradition. Around the Masuda area, adding grilled ayu has been the norm. To make dashi stock for the soup, slowly grill the ayu and dry them. After putting the soup and mochi in the dish, garnish the soup with an entire ayu on top. Ayu’s dashi makes this zoni full of umami with a light aftertaste.
