Salmon Sashimi Bento (torched) Recipe

Rinse and cook rice

Rinse 1 cup short-grain sushi rice under cold water until the runoff runs nearly clear (about 3–4 rinses). Drain and transfer to a rice cooker or small pot. Add 1.1 cups water. Cook according to your rice cooker, or bring to a boil on medium-high, then reduce to low, cover, and simmer 12–14 minutes until water is absorbed. Remove from heat and rest covered 10 minutes.

Season rice

While rice rests, stir together 1 tbsp rice vinegar, 1 tsp sugar, and 1 tsp salt until dissolved. Transfer rice to a shallow bowl, gently fold in vinegar mixture using a cutting motion to avoid mashing grains, and fan or let cool to warm (not hot). Keep covered until assembling bento.

Make glaze

In a small bowl combine 2 tbsp mirin, 1 tbsp light soy sauce, 1 tsp rice vinegar, 1 tsp sesame oil, and 1 tsp granulated sugar. Whisk until sugar dissolves. Reserve 1 tsp of the glaze for finishing; the rest will be used to lightly marinate the salmon.

Marinate salmon briefly

Pat the sushi-grade salmon slices dry on paper towel. Arrange slices on a plate and brush or drizzle the remaining glaze lightly over the top (just enough to coat surfaces). Let sit 5–8 minutes at cool room temperature or in the fridge for up to 15 minutes — do not over-marinate or let sit for hours because sashimi should remain very fresh-tasting.

Torch the salmon

Working in a well-ventilated area, use a kitchen blowtorch to lightly sear the top of each salmon slice. Hold the torch 3–4 inches away and move continuously so you get a thin, even char without cooking through (about 5–10 seconds per slice depending on flame). Aim for a lightly browned, slightly smoky surface while the interior stays raw and silky.

Finish and plate

Immediately after torching, brush the reserved 1 tsp glaze over the torched surfaces for shine and flavor. Arrange a bed of seasoned sushi rice in each bento compartment, lay the torched salmon slices over the rice, and drizzle a little soy sauce at the edge of the plate for dipping (or serve soy in a small cup).

Sprinkle 2 tbsp thinly sliced scallions and 1 tsp toasted sesame seeds over the salmon. Add microgreens or shiso leaves and a small dab (about 1 tsp) of yuzu kosho or a few drops of yuzu juice if using. Place pickled ginger and a small portion of wasabi at the side for traditional accompaniments.

If using, arrange steamed broccoli florets and tamago slices in separate bento compartments. These can be warm or at room temperature. For a balanced bento, allot about 1 cup broccoli and 3 slices tamago per serving.

Serve immediately once torched and assembled. Eat within the same sitting for best texture and food safety. Leftover raw-torched salmon should be refrigerated and consumed within 24 hours.
