Thai Grilled Whole Fish With Coriander-Chili Sauce

The Spruce / Maxwell Cozzi

Ingredients
1 small trout, cleaned
1 dash sea salt, or kosher salt
2 limes, plus wedges for serving
1 cup vegetable oil, for deep-frying

For the Sauce:

1/3 cup water
1/2 tablespoon tamarind paste
3 cloves garlic
1 heaping teaspoon brown sugar
1 thumb-sized piece galangal, or ginger, peeled and sliced
1 cup fresh cilantro leaves and stems, plus more for garnish
2 tablespoons fish sauce
1 to 2 fresh red chiles, minced, deseeded for less heat
1/2 red bell pepper, deseeded and diced

Pat fish dry. Make 2 to 3 diagonal cuts on the side of the fish (with the blade of the knife on an angle facing the head). The cuts should be several inches apart.

Squeeze the juice of 1 to 2 limes over and inside fish. Sprinkle surface with sea salt and set aside while you prepare the sauce.

fish with salt and lime juice 
Place water, tamarind (or lime juice + soy sauce), garlic, sugar, galangal (or ginger), coriander, fish sauce, and chiles in a food processor. Process well (or chop and mix by hand).

Pour the sauce into a saucepan. Add the diced pepper and simmer over medium-low heat for 5 to 8 minutes. Taste the sauce for salt and sweet-sour balance, adding more fish sauce if not salty enough, and more sugar if you find it too sour. Cover and keep warm while you cook the fish.

sauce in a saucepan 
Grill the fish on the barbecue over medium-high heat (375 F), or deep-fry it in a wok or large frying pan with 1 cup canola or other vegetable oil. Allow to grill or fry about 5 minutes on each side, or until the flesh has browned and flakes easily. Don't flip the fish too early, or the skin will stick to the pan/barbecue. Allow it to cook at least 2 minutes before turning.
