Slice fish across the grain into thin (1/8-inch thick) medallions about 1 1/2-inches in diameter. Place a sheet of plastic wrap in the palm of your hand and lay a piece of fish on it. Put 1 rounded tablespoon sushi rice on the fish, gather up the edges of the plastic, and twist to form the combination into a ball.
Keep sushi cold until ready to serve.
