Kombu-Cured Salmon with Fresh Yuzu Kosho image

Number Of Ingredients 11

1 1/2 pounds piece boneless salmon fillet
4 pieces 6x5-inch pieces dried dashi kombu (should be flat and not wrinkled)
1/2 piece lemon, thinly sliced, seeds removed
2 tablespoons mirin (sweet Japanese rice wine)
1 tablespoon mild miso (such as white or yellow)
1 teaspoon soy sauce
1 piece jalapeño, seeds removed, chopped
1 piece serrano chile, seeds removed, chopped
1 pinch Kosher salt
3 tablespoons Zest and juice of 1 yuzu or zest of ⅛ white grapefruit, ½ lemon, ½ lime, and 1 tablespoon mixed juice from all three
2 pieces Yuzu or lime wedges (for serving)

Steps:

Slice salmon on a diagonal into four 1"-1¼"-thick fillets. Place 2 kombu sheets in a 13x9" glass baking dish or other nonreactive vessel. Lay salmon on top of kombu and top with remaining kombu so that salmon is completely covered. Lay lemon slices on top. Cover and chill at least 12 hours and up to 2 days.
Whisk mirin, miso, and soy sauce in a small bowl until smooth. Set glaze aside.
Toss jalapeño and serrano chile with a large pinch of salt on a cutting board and mash with the side of a chef's knife until a coarse purée forms. Transfer to a small bowl. Mix in yuzu zest and juice; season yuzu kosho with salt. Set aside.
Heat broiler. Lightly coat a broilerproof baking sheet with nonstick spray. Uncover salmon and transfer to baking sheet; discard kombu and lemon. Spread reserved glaze evenly over top of salmon and broil until flesh is very dark around the edges and opaque throughout, about 4 minutes.
Top salmon with reserved yuzu kosho and serve with yuzu wedges for squeezing over.
