Method
In a food processor, combine the lime pickle, fresh coriander, lime juice, garlic, green chili, and extra virgin olive oil. Blitz until it forms a coarse, vibrant paste.
Place the mackerel fillets flesh-side up in a mixing bowl or on a plate. Spoon half of the coriander and lime paste over the flesh, rubbing it in gently. Leave to marinate at room temperature for 15 minutes.
Transfer the remaining paste to a small bowl. Whisk in a splash of water to loosen the mixture into a spoonable dressing consistency. Set aside.
Place a grill pan over high heat and let it preheat until very hot and just beginning to smoke.
Pat the skin side of the mackerel dry with a paper towel. Rub the skin with the standard olive oil and sprinkle evenly with sea salt. Place the fillets skin-side down on the hot grill pan. Cook without moving them for 3 minutes.
Carefully flip the mackerel using a fish spatula. Cook on the flesh side for 1 more minute until just cooked through. The internal temperature should reach 63C or 145F.
Transfer the cooked mackerel to warmed serving plates. Spoon the reserved, loosened coriander and lime pickle dressing generously over the fillets. Serve immediately.
Chef's Notes
- Mackerel is a dark, oily fish that handles aggressive flavors beautifully. The bitterness and saltiness of Indian lime pickle cut right through the richness.
- When buying mackerel, look for bright, clear eyes and stiff, firm bodies. Oily fish degrades faster than white fish, so impeccable freshness is non-negotiable.
- Scoring the skin of the mackerel lightly with a sharp knife before cooking can further help prevent the fillets from curling up when they hit the hot grill.
- Do not marinate the fish for longer than 30 minutes, as the lime juice will begin to cure the flesh (ceviche style) and alter the final cooked texture.
Storage
Refrigerator: 24 hours — Store in an airtight container. Best consumed fresh as mackerel loses texture quickly.
Reheating: Reheat gently in a 150C/300F oven until just warm. Microwave reheating will make the fish rubbery.
