Mukimono, the Japanese art of fruit and vegetable carving
Mukimono has only recently become a phenomenon on Instagram thanks in large part to one user, Gaku. The art has been dated back over a thousand years, but the practice didn't become popularized until the Edo period from 1603 to 1867. Some people, looking at the beautiful designs, may be inspired to try it for themselves but should know that specialist knives are used for the art.
Fruit and vegetables carved in this way are often used as a garnish on a plate. The purpose of mukimono cut vegetables and fruit is mainly to increase the appeal of a prepared dish, but they are still perfectly edible if prepared correctly.
