One shouldn’t really eat freshwater fish raw but I make an exception for this splendid dish, known as koi arai (lit. ‘washed carp’). Slices of koi carp sashimi are placed in hand-warm water for a few moments, then chilled in ice water. The flesh firms up and curls slightly, and is served on a bed of ice cubes and taken not with soy sauce, but with vinegared white miso (seen to the left). I ate this dish at a local restaurant called Iseki.
