Marinated Fresh Tuna and Grated Nagaimo Rice Bowl

Marinated Fresh Tuna and Grated Nagaimo Rice Bowl

This is a refreshing rice bowl with marinated fresh tuna (maguro) and grated nagaimo yam. The key to the flavor is the cooked soy sauce mixture. I usually sprinkle shiso leaves on top, but you can use chopped green onion or grated wasabi instead. You can also lightly sear the surface of the tuna block.

Ingredients: 1 serving

Fresh sashimi grade tuna
100 g
Nagaimo yam
200 g
Plain cooked rice
1.5 - 2 regular rice bowls
Soy sauce
2 tablespoons
Sake
2 tablespoons
Mirin
3 tablespoons
Shiso leaves, Japanese leek, or grated wasabi
to taste

Steps

1. Put the soy sauce, sake and mirin in a pan and bring to the boil to evaporate the alcohol. Let cool.
2. Slice the tuna block to 5 mm thick. Put into the boiled soy sauce combination, cover with plastic wrap and marinate in the refrigerator for about an hour.
3. Put the rice into a bowl and let it cool down a bit. Grate the nagaimo yam in a mortar and put 2/3 on top of the rice.
4. Arrange the tuna slices on top of the grated nagaimo in the bowl, and pour the rest of the nagaimo on top. Drizzle on some of the marinade to taste, and put the garnishes on top.
