Mild Coconut Fish Curry

This South Indian-style fish curry is built on a spice base that’s aromatic and warming rather than fiery. Mustard seeds, fenugreek, turmeric, cinnamon, and tamarind create a complex, layered flavor that wraps around the fish without overwhelming it. The “mild” in the name means gentle warmth, not bland.

Shallots and garlic fried with popping mustard seeds set the foundation. Cubed fish gets a quick flour dusting and sear on both sides before the spices and coconut liquid go in for a 20-minute covered simmer. The flour coating helps the fish hold together in the sauce and gives the curry a slightly thicker body.

Tamarind pulp dissolved in liquid adds a fruity, sour tang that’s characteristic of Kerala and coastal Indian fish curries. Grated coconut stirred in at the end rounds everything out with rich, creamy sweetness.

Chef Tips

• Fry the mustard seeds until they start popping. That pop means the flavor oils are releasing. Unpopped seeds taste bitter and raw
• Dust the fish lightly with flour before searing. This creates a thin crust that keeps the cubes from falling apart during simmering
• Use coconut milk instead of water to dissolve the tamarind for an even richer, more cohesive sauce
• Simmer covered so the fish steams gently. Uncovered boiling will break it apart

Variations

• Use swordfish, cod, or any firm white fish that holds its shape in a curry
• Add a handful of fresh curry leaves with the mustard seeds for a more authentic South Indian aroma
• Stir in a few tablespoons of coconut cream at the very end for extra richness
