Step 1

Preheat oven to 350°. Pat salmon dry, then season with kosher salt. Heat 1 Tbsp. oil in a large ovenproof nonstick skillet over medium. Cook salmon (skin side down if it has skin) until well browned underneath, 6–8 minutes, then transfer to oven. Roast until flesh is opaque and flakes easily with a fork, 8–12 minutes.

Step 2

Meanwhile, cook chiles, ginger, coconut flakes, peanuts, and remaining 5 Tbsp. oil in a small saucepan over medium heat, stirring often, until coconut and peanuts are golden, 8–10 minutes. Transfer coconut-chile crunch to a heatproof bowl and let cool slightly.

Step 3

Using a small sharp knife, cut peel and white pith from citrus, leaving as much flesh behind as possible. Cut flesh from cores in a variety of shapes and sizes and arrange on plates. Break salmon into big pieces and divide among plates, arranging on top of citrus.

Step 4

Stir vinegar into coconut-chile crunch and season with salt (it will probably need a few pinches). Spoon over salad and sprinkle with sea salt.
