Ingredients
- 2 pieces Mackerel fillets (Saba)
- 1 teaspoon Sea salt
- 3 large Eggs
- 1.5 cups Dashi stock
- 3 tablespoons Soy sauce
- 2 tablespoons Mirin
- 1 tablespoon Sugar
- 4 pieces Shiitake mushrooms
- 1 medium Carrot
- 4 ounces Daikon radish
- 1 tablespoon Vegetable oil
- 2 cups Cooked short-grain white rice
Instructions
- 1
Salt the mackerel fillets and let them sit for 15 minutes, then pat dry and grill over medium-high heat until the skin is crispy and the flesh is cooked through.
- 2
Prepare the Nimono by peeling and cutting the carrot and daikon into bite-sized chunks.
- 3
In a small pot, combine 1 cup of dashi, 2 tablespoons of soy sauce, 1 tablespoon of mirin, and the vegetables; simmer until tender (about 15-20 minutes).
- 4
For the Tamagoyaki, whisk eggs with 2 tablespoons of dashi, 1 teaspoon of sugar, and 1 teaspoon of soy sauce.
- 5
Lightly oil a square tamagoyaki pan and pour a thin layer of egg mixture, rolling it as it sets; repeat until all egg is used.
- 6
Slice the finished Tamagoyaki into 1-inch thick pieces.
- 7
Allow all components to cool slightly to room temperature before packing to prevent steam buildup in the bento box.
- 8
Assemble the bento by placing rice on one side, the grilled fish on top, and nesting the Nimono and Tamagoyaki in the remaining compartments.
