A vibrant coastal curry featuring tender fish and potatoes simmered in a fragrant, tangy gravy of rehydrated red chillies, coconut, and garlic.
Marinade spice
3 gMixed with lime and sugar to coat the fish (step 1)Red chilli paste spice
8 gSoaked and puréed with the aromatics (step 2)Everything else
Method
- Whisk 2.1 g granulated sugar, 15.3 g lime juice, a pinch of salt, and the marinade spice in a dish, then rub the mixture thoroughly over 750 g fish and refrigerate, covered, for 15 minutes.
- Immerse the red chilli paste spice in lukewarm water for 15 minutes, then drain, keeping the soaking liquid aside, and slit the chillies open to scrape out the seeds.
- Transfer the softened chillies into a blender with 30 g coconut, 18 g garlic, 15 g white malt vinegar, and enough of the reserved soaking water to grind everything into a smooth, thick purée.
- Set a broad pan over medium-low heat, warm 1 tablespoon oil, and gently fry the blended paste for 1 to 2 minutes, stirring constantly to preserve its bright scarlet tone without browning.
- Place 300 g potato in a pot with 250 ml water, bring up to a rolling boil, then clamp on a lid, drop the heat, and simmer for 10 minutes.
- Tip the marinated fish, all of its marinade juices, and the sautéed chilli paste into the pot of potatoes, pour over another 250 ml water, and add salt to taste.
- Cover the pot and simmer over low heat for 10 minutes until the fish flakes cleanly and the potatoes are completely tender.

Skinless firm white fish fillet

Firm white fish filletUse the same weight; remove any skin and cut into even pieces. Cook gently for the same short time.
Skinless boneless fish filletUse the same weight; check for bones and simmer 5–8 minutes until just opaque. It may be softer, so stir less.
Firm white fishUse the same weight; clean, skin and cut into chunks. Cooking time is similar, but check for bones.

Ground turmeric

Ground gingerUse 50% of the weight. Mimics turmeric's warm, earthy, rhizome background, but provides none of the golden-yellow colour.
SaffronSteep 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.

Granulated sugar

JaggeryUse equal weight; grate or shave finely so it dissolves rapidly, giving a warm, caramel-like sweetness and slightly darker sauce.

Lime juice

Lemon juiceUse equal volume or weight; slightly sweeter and less pungent, but otherwise an imperceptible swap.
Dried mango powderUse 25% of the weight; imparts dry, fruity sourness, best stirred in right at the end of cooking.
Tamarind extractUse 50% of the weight; delivers pleasant fruity tang but turns pale sauces considerably darker.

Oil

Vegetable oilUse the same weight. It is neutral and behaves the same in frying and tempering; no noticeable change in flavour.
Corn or vegetable oilUse the same weight. Neutral and good for high heat; the dish will taste virtually the same.
Groundnut oilUse the same weight. It has a mild nutty flavour and is good for Indian cooking; heat until just hot, not smoking, so the nuttiness does not dominate.

Potato

EggplantUse equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.
PaneerUse 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.
Dried chickpeaUse 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

Dried red chilli

Dried kashmiri chilliUse equal weight whole. Fry in hot oil or ghee as tempered spice; gives a richer red colour with slightly milder heat.
Red chilli powderUse 50% to 70% of the weight. Stir into the oil with ground spices; distributes heat evenly throughout the dish without whole chilli skins.

Desiccated coconut

Grated desiccated coconutUse equal weight directly; it is the identical ingredient under a different label.
Fresh coconutGrate finely and use 130% to 140% of the weight to compensate for higher moisture; toast gently in a dry pan over low heat if a dry texture is needed.
Dried coconutGrate finely using a microplane and use equal weight. Offers a slightly oilier, toastier coconut profile.

Garlic

Garlic pasteUse equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.
Garlic powderUse 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.
ShallotUse 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

White malt vinegar

White vinegarUse 90% of the weight. It is sharper and lacks the mild malty grain undertone, so temper with a tiny pinch of sugar if needed.
Lemon juiceUse 100% of the weight. Best for marinades or quick chutneys; imparts fresh citrus flavour instead of fermented acidity.
