Sushi Rice:

For the seasoning, heat rice vinegar with sugar and salt in a stove pot or microwave. Mix until fully dissolved. Cook sushi rice with water in a thick bottom pot (or rice cooker). Once ready, transfer rice to wooden or plastic container. Do not cover. Pour seasoning evenly over rice and mix with wooden spoon in a cutting motion. Mix through black sesame seeds.
 

To Assemble:

Divide hot cooked rice between 4 bowls, top with warmed teriyaki beef, avocado slices, carrot ribbons, cooked corn and pickled ginger. Top with mayonaise and sprinkle with sesame seeds and nori seaweed if using. 

We like to serve wasabi and soy sauce in small bowls alongside.
