Blue Crab Recipe

Rinse the short-grain rice under cold water until the water runs nearly clear (about 4–6 rinses) to remove surface starch.

Combine rinsed rice and 2.2 cups water in a rice cooker or a heavy-bottomed pot. Let soak 20–30 minutes at room temperature for even cooking.

Cook rice in the rice cooker according to manufacturer's instructions or bring to a boil in the pot, reduce to low, cover, and simmer for 12–14 minutes. Remove from heat and let steam, covered, for 10 minutes.

While rice cooks, warm the rice vinegar, sugar, and salt in a small saucepan or microwave just until sugar dissolves. Do not boil.

Transfer hot rice to a wooden or wide shallow bowl (hangiri or large mixing bowl). Gently fold the vinegar mixture into the rice using a rice paddle or spatula with cutting-and-fanning motions to cool and coat the grains without crushing them. Fan the rice as you fold to achieve a glossy finish. Allow rice to come to near-room temperature (~15 minutes).

If using whole cooked blue crab, pick meat from shells and pat gently with paper towels to remove excess moisture. Measure 8 oz of picked crab meat.

In a bowl, combine crab meat, 2 tablespoons Japanese mayonnaise, 1/2 teaspoon light soy sauce, 1 teaspoon yuzu (or lemon) juice, 1 tablespoon thinly sliced scallion, and shredded shiso (or cilantro).

Gently fold ingredients together so the crab lumps remain intact; avoid overmixing. Season with 1/4 teaspoon kosher salt and a pinch (1/8 tsp) of freshly ground black pepper. Taste and adjust: add a touch more mayo or acid if needed.

If using sesame oil, stir in 1/4 teaspoon for a whisper of nutty aroma. If you prefer a chilled filling, cover and refrigerate up to 30 minutes; bring back to cool-but-not-cold before assembling.

Cut each nori sheet into 2 (long) strips ~3–3.5 cm (1.2–1.4 in) wide — you should get about 4 strips from 2 sheets, enough for approximately 8 small gunkan. Toast nori briefly over a flame or in a dry skillet if not pre-toasted.

Wet your hands lightly with water mixed with a little rice vinegar to prevent sticking. Take about 1.5 tablespoons of sushi rice and form an oblong ball (nigiri-size) with a slightly flattened top. Repeat to make 8 rice bases.

Wrap a nori strip around each rice base, overlapping the ends slightly and sealing the seam by wetting the edge with a drop of water. The nori should rise slightly above the rice to create a rim for the filling.

Spoon roughly 1 heaping tablespoon of the crab filling into the nori cup for each gunkan, mounding slightly but keeping the crab lumps intact.

If using tobiko or masago, dot about 1/4 teaspoon on top of each crab mound for color and texture. Garnish each piece with a few microgreens or a small sliver of shiso.

Plate the gunkan with pickled ginger and wasabi on the side. Serve immediately at cool-room temperature (do not serve crab too warm).
