Black pomfret is steeped in a tangy lime-and-turmeric rub, coated with a warm, coarsely ground spice paste, and pan-roasted inside a leaf or foil parcel until tender and aromatic.
Initial marinade spice
3 gMixed into the lime juice and salt for the primary rub (step 1)
Remove the head and fins from 1000 g fish, then slash several deep diagonal cuts across both sides of the flesh.
Combine the initial marinade spice with 30.6 g lime juice and 2.9 g salt in a bowl. Rub this seasoned juice over the fish and into the slashes, then set aside in a shallow dish.
Warm a dry tawa or frying pan over medium-low heat. Add the whole roasting spices and toast for roughly 30 seconds until fragrant and slightly darkened.
Pound the toasted spices to a coarse consistency with a mortar and pestle, or pulse them in a spice mill. Transfer to a bowl and mix with 4.2 g granulated sugar and salt to taste, adding a trickle of water if needed to bring it together into a thick paste.
Rub the spice paste thoroughly across the entire fish, pushing it deep into the incisions.
Encase the fish tightly in a softened banana leaf (pinning the edges with cocktail sticks) or a sheet of kitchen foil.
Place a griddle or non-stick frying pan over medium heat. Once hot, add the wrapped fish parcel and cook for 5 minutes per side, until the fish is cooked through, then serve hot.
Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
Use 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.
Allspice berries
Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.
Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.
