Make both the boiled marinade and sushi vinegar in the microwave, so you don't have to dirty a pot. Tuna marinated in this sauce is really delicious!
Recipe background:
I made tekka don, a favorite of my kids, because tuna blocks were on sale.

Steps

1

Put the mirin and sake in a deep microwave-safe bowl and microwave until boiling. Mix in the soy sauce. Once cooled, slice the tuna and marinate it in the sauce.
2

Combine the sushi vinegar ingredients (rice vinegar, sugar, salt) and microwave for 1 minute, then stir. Add the dried kelp to the rice and cook the rice a little firm. Mix the sushi vinegar into the cooked rice.
3

Scoop the sushi rice into bowls, sprinkle with crumbled nori, arrange the marinated tuna on top, and drizzle with a little marinade. Adults can add wasabi if desired.
