• 1/2 tsp. black peppercorns, coarsely crushed
• 2 fresh green Thai, cayenne, or serrano chiles, stems removed, cut in half lengthwise (do not remove seeds)
Mix salt, turmeric and garlic in a small bowl. Sprinkle this rub over the top of the salmon fillet, and rub it in. Refrigerate, covered, at least 30 minutes or as long as overnight, so flavors permeate the fish.
Heat the oil in a large skillet over medium heat. Add the salmon, spice-covered side down, and sear it for about 2 minutes to brown the fish and cook the turmeric. Turn the fillet over and sear the underside until browned, about 2 minutes.
Pour the coconut milk in a measuring cup, and add the peppercorns and the chiles. Stir, and pour this over the fish. Lift the fillet with a spatula and tilt the skillet slightly to allow the spiced coconut milk to run under it and release the browned bits of garlic, spice and fish. Reduce the heat to medium-low, cover the skillet, and braise the salmon, spooning the sauce over it occasionally, until the flesh is barely starting to flake, 3 to 5 minutes. Transfer the fish to a platter, pour the curry over it, and serve.
