Grilled Mahimahi with Tamarind Glaze

This grilled mahimahi with tamarind glaze is a bright and aromatic seafood dish that perfectly balances sweet, sour and salty flavours. Mahimahi is an excellent choice for the grill, as its firm texture holds up beautifully over high heat while soaking up the punchy Asian-inspired marinade. The star of the show is the tamarind pulp, which provides a unique, fruity tartness that cuts through the richness of the fish, creating a sophisticated main course that is surprisingly simple to prepare.

As a diabetes-friendly option, this recipe focuses on lean protein and vibrant, natural seasonings rather than heavy fats.

Ingredients for Grilled Mahimahi with Tamarind Glaze

  • 120ml tamarind pulp (from a pliable block)

  • 240ml boiling-hot water

  • 3 tablespoons plus 1 teaspoon packed palm or dark brown sugar

  • 2 tablespoons soy sauce

  • 2 tablespoons Asian fish sauce

  • 1 tablespoon fresh lime juice

  • 10 (1- to 1 1/2-inch-thick) pieces mahimahi fillet with skin (170g each)

  • 2 tablespoons vegetable oil

  • 1 teaspoon kosher salt

How to make Grilled Mahimahi with Tamarind Glaze

Soak tamarind pulp in boiling-hot water in a small bowl, stirring occasionally, until softened, about 5 minutes. Pour mixture into a medium-mesh sieve set into a bowl, then force pulp through sieve, discarding seeds and fibers. Add brown sugar, soy sauce, fish sauce, and lime juice, stirring until sugar is dissolved.

Prepare grill for cooking over medium-hot charcoal (moderate heat for gas).

Brush fish all over with oil, then sprinkle with salt. Grill, skin sides down, on lightly oiled grill rack, covered only if using gas grill, until skin is crisp, about 4 minutes. Turn fish over and grill until just cooked through, about 6 minutes more. Brush tamarind sauce all over fish and grill 1 minute.

Serve with remaining sauce.
