8 ounces raw fresh tuna fillet
2 cups cooked sushi rice
1 to 2 tablespoons wasabi paste, to taste
1. Slice the tuna into one-inch by two-inch rectangles, about a quarter-inch thick.
2. Take a small amount of the sushi rice and cradle it in your right hand at the base of your finger. Using your hands, take the rice and form a rectangular shape to match the tuna slices.
3. Spread ¼ to ½ teaspoon of wasabi paste onto the slice of tuna. Place the rice block on top, and press gently to shape the sushi. Repeat with remaining ingredients to make several sushi pieces.
4. Serve as desired.
