“Dashi is like the key actor in a movie,” says 83-year-old Chobei Yagi, whose 275-year-old store, Tokyo’s Yagicho Honten, specializes in katsuobushi and other dried foods. “But dashi always plays the supporting role, never the star.”
Most katsuobushi today comes pre-sliced in plastic bags, which is convenient and allows one to make dashi from scratch in less than 15 minutes, but there is another level of truly great katsuobushi — artisanal arabushi-style katsuobushi and the maturer karebushi- and hongarebushi-style katsuobushi. These are sold in thick blocks, with brown surfaces coated in sun-dried mold. They look more like works of art than food, and maybe they are.
