Himono literally means “dried things”, but it commonly refers to dried seafood, which generally contains more calcium, phosphorous, iron and potassium than raw seafood. Popular himono includes sardine, horse mackerel and especially squid, which is known as surume. There are numerous ways to make himono: maruboshi refers to fish that are dried after being soaked in salt water. Mirinboshi refers to seafood that is dried after being soaked in mirin. Himono is served as a popular traditional breakfast.
