- 3 1/2 cups short-grain rice
- 3 3/4 cups cold water
- 1/3 cup plus 1 1/2 Tbs. water
- 2 tsp. plus 1/2 cup unseasoned rice vinegar
- 2 Tbs. wasabi powder
- 1/3 cup sugar
- 1 tsp. salt
- 6 sheets toasted nori seaweed, about 7 by 8
- 1/4 cup sesame seeds, toasted in a dry fry pan
for 3 to 5 minutes
- 3/4 English (hothouse) cucumber, peeled and
cut into thin strips 6 inches long
- 1 1/2 avocados, pitted, peeled and cut into
slices 1/4 inch thick
- 6 oz. cooked fresh crabmeat, flaked into pieces
- 1/2 cup Japanese soy sauce
- 3/4 cup pickled ginger slices
In a small bowl, combine the 1/3 cup water and the 2 tsp. vinegar. In another small bowl, combine the wasabi powder and the 1 1/2 Tbs. water, stir to form a smooth paste and let stand for 10 minutes. Divide in half and set half aside.
In a small saucepan over low heat, combine the 1/2 cup vinegar, the sugar and salt and cook, stirring occasionally, until the sugar and salt are dissolved, about 3 minutes. Set aside to cool.
Transfer the hot rice to a large bowl. Drizzle with two-thirds of the vinegar-sugar mixture and gently fold into the rice. Add only as much as the rice will absorb without becoming mushy. Cover with a damp kitchen towel.
Place a bamboo sushi mat on a work surface with the bamboo strips running horizontally. Place 1 nori sheet aligned horizontally on the mat, shiny side down, with the edge nearest you. Dip your hands into the vinegar-water mixture and spread about 2 cups of the rice in an even layer over the nori sheet, leaving the top one-fourth uncovered. Smear a thin strip of wasabi horizontally across the middle. Sprinkle sesame seeds over the wasabi, followed by a few cucumber strips, an even row of avocado slices and one-sixth of the crabmeat. Lift the nearest edge of mat, nori and rice over the filling to seal it inside. Continue to lift and press on the mat to form a snug cylinder about 2 inches wide. Dipping a sharp knife in water before each cut, cut the roll in half. Cut each half into 4 equal pieces. Repeat with the remaining 5 nori sheets.
Serve the sushi with the reserved wasabi, the soy sauce and the pickled ginger. Provide small dishes for mixing a small amount of wasabi with soy sauce to use as a dipping sauce.
