buy the fish. Japanese markets will carry high quality fish trimmed into pieces that are ready to be sliced and served sashimi-style. However, many fish markets and high-end supermarkets carry fish equally suitable for making sashimi. Nearly any kind of fish can be used—freshwater and saltwater varieties apply. Popular choices include mackerel, tuna, snapper, halibut, salmon, sea bass, eel, and scallop.
