Marinate fish fillets with turmeric powder and salt, then set aside for 15 minutes to let the flavors infuse.
Heat coconut oil in a large skillet over medium flame. Add cumin seeds, and when they start to sizzle, add sliced onions. Sauté onions until golden brown, about 5 minutes, to develop sweetness.
Add chopped tomato and cook until soft, about 3 minutes. Stir in red chili powder and coriander powder, cooking for 1 minute to toast the spices.
Grind fresh grated coconut and tamarind paste with a few tablespoons of water into a smooth paste. Add this to the pan and simmer gently for 5 minutes on low heat to blend flavors and release the coconut aroma.
Nestle marinated fish fillets into the simmering sauce in a single layer. Cook uncovered on medium-low heat for 6–8 minutes, spooning the sauce over the fish occasionally. Avoid over-stirring to prevent breaking the fillets.
Check the fish for doneness – it should flake easily but remain moist. Taste and adjust salt as desired. Rest for 2 minutes off heat before serving for the flavors to settle.
