A Bengali-style prawn curry with a smooth onion and coconut paste, warm whole spices and a mustard finish. It tastes rich and gently sweet, with mild heat from chilli and green bird’s eye chilli.
Prawn marinade turmeric
1.5 gMixed with the prawns and salt before frying (step 1)
Coat 300–375 g large raw prawn, shelled and deveined with tails left on, with 1.5 g ground turmeric and salt to taste in a bowl. Leave aside.
Blend 150 g onion, 10 g fresh ginger, 6 g garlic, 4 g green bird’s eye chilli and 50 g grated coconut with 2–3 tbsp water until you have a thick, smooth paste. Set aside.
Heat half of 54 g vegetable oil in a frying pan over medium heat. Fry the prawns for 20 seconds on each side, until the edges begin to colour but the centres are not cooked through. Lift out and drain on kitchen paper.
Heat the rest of the oil in a heavy-based saucepan over medium heat. Add the whole spices for the oil and fry for 30 seconds. Add the onion paste and cook for 5–7 minutes, stirring often and scraping the base of the pan. Stir in the ground chilli for the sauce, 2.1 g granulated sugar and salt to taste; cook for 1 minute. Pour in 101 g coconut milk and 100 ml water, then simmer gently on low heat. Return the prawns to the pan and simmer for 3–4 minutes, until cooked through.
Mix 1.2 g English mustard with 1 tbsp water, then stir it into the curry. Scatter coriander leaves to taste over the top. Serve warm with boiled rice.
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 equal weight; simmer gently over low heat to prevent curdling. Imparts a comparable rich texture, though it adds dairy richness without any coconut fragrance.
Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.
Use 20% to 25% of the weight (1 g for every 4 to 5 g fresh). Stir into the gravy; adds peppery heat and warmth, though it misses the crisp, zesty kick of raw root.
Use 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.
