3 rice cooker cups' worth before cooking (540 g uncooked)
★If using rice vinegar
★If using white wine vinegar
1 heaping teaspoon
Prepare the ingredients. Cut 1/2 an avocado into 6 pieces. Use vinegared sushi rice or plain rice.
Line a makisu (bamboo sushi rolling mat) with plastic wrap.
Put a half-sheet of nori seaweed on the plastic wrap and cover it with rice. Use about 120 to 140 g of rice.
Flip the nori and rice over to put the rice on the bottom. Top with the crabsticks, lay down a line of mayonnaise, and then put on the avocado slices.
Flip over the edge of the sushi mat and press down tightly in the middle with your hands. By pressing down like this you will elminate any gaps between the fillings and the rice, and the rolls will be very tidy.
Roll the mat one more time and press down again.
This is how the roll looks when the mat is opened up. It's done. Cut the roll on a cutting board.
Cut into 6 pieces. Wipe the knife blade with a tightly wrung out moistened kitchen towel after each cut to cut the roll cleanly.
You can sprinkle the surface of the rolls with sesame seeds or flying fish roe (tobiko). If you are adding cucumber, cut it into thin strips and add it before you add the avocado.
Flaked salmon and avocado rolls: I used storebought "salmon flakes" (available at Japanese groceries) and avocado.
Tuna and avocado rolls: Drain the canned tuna, mix with mayonnaise and roll.
Wiener sausage and cucumber rolls.
This was for a potluck party. I cut the California rolls into 8 pieces, and decorated them with cut out carrot and colored usuyaki tamago (thin omelette).
To make sushi rice: Bring the vinegar, sugar and salt to a boil and cool. Mix it into the rice when the rice is cooked.
I have a recipe for making sushi rice using Japanese rice vinegar, with the appropriate amounts of sugar and salt (Recipe ID: 1512838).
You can use white wine vinegar made by overseas makers like Heinz (Recipe iD: 1263403).
Story Behind this Recipe
I live in Canada. My school doesn't have a lunch program, so they bring bento. They bring sushi rolls to school once a week.
To make these rolls with a silicone sheet and no plastic wrap, see (Recipe ID: 1263465). For California rolls using crabstick flakes, see (Recipe ID: 1279378).
When I serve this to a lot of people, at a party for instance, I cut the rolls into 8 pieces.
