2 tablespoons butter
1 medium sweet onion, cut into quarters lengthwise, then sliced crosswise
1/2 of a small red and 1/2 small green bell pepper, cut into matchsticks
1 14 ounce can coconut milk (unsweetened)
2 1/2 – 3 1/2 tablespoons red curry paste
1 tablespoon fish sauce
3 tablespoons fresh lime juice
1-2 teaspoons brown sugar, to taste
4 dried kaffir lime leaves, optional (found in most Asian markets)
2 or 3 tablespoons fresh cilantro, chopped
1 lb black sea bass fillets or other firm flesh fish
10-15 large or extra large shrimp, deveined
10 mussels, cleaned, debearded and steamed separately
sea salt to taste
Heat butter in a heavy saute pan over medium heat. Saute the onions and bell peppers until they are semi-soft, 5-7 minutes.
Add Thai red curry paste to the onions and peppers and stir well over the heat to mix. Pour in the coconut milk, lime juice, fish sauce, brown sugar, and kaffir lime leaves (if using). Simmer over low heat, uncovered, for around 10 minutes so the flavors can blend and the broth can reduce slightly.
In the meantime, rinse the fish and shrimp with cold water, pat dry, and lightly season with salt. Place the fish and shrimp in the saute pan, and nestle them into the broth as much as possible. Simmer on very low, covered, for 5 minutes, mix in steamed mussels and simmer cover another 5-7 minutes until the fish flakes easily. During the last minute or two of cooking, add chopped cilantro. Serve hot over Jasmine rice in a bowl along with broth. Enjoy!
