Plan ahead: plus at least 4 hours resting, and overnight is better.

The re-engineeringCoconut oil down from about 45 g to 10 g, half of it stirred in raw at the end where you can actually taste it; the body now comes from 120 g of shallots cooked right down and a full three pieces of kudampuli rather than from fat.

This is the archetype of the Kerala red fish curry and the flagship of this chapter: fiery, thin, brick-dark, soured with kudampuli and cooked in an unglazed clay pot. It is a Central Travancore dish, Kottayam-style, and the households that own it cook it in the evening to eat at noon the next day. That is not thrift. Kudampuli is the one souring agent in Kerala that makes a curry improve overnight rather than flatten, and the mechanism is worth knowing before you cook it.

Before you start: Soak the kudampuli first — it needs 15–20 minutes and everything else takes less. Slice the shallots before you light the flame; 120 g takes five minutes and the pot will not wait.

Ingredients — tap to tick off

  • 3 pieces kudampuli (about 8 g), rinsed
  • 60 ml warm water, for soaking
  • 10 g (2 tsp) coconut oil, divided: 5 g and 5 g
  • 120 g (about 12) shallots, thinly sliced
  • 15 g (a 3 cm piece) ginger, julienned
  • 10 g (about 3 cloves) garlic, sliced
  • 2 green chillies (about 10 g), slit lengthways
  • 14 g (2 tbsp) M05 fish masala
  • 3 g (1 sprig) curry leaves
  • 350 ml water
  • 3 g (½ tsp) M07 salt, or plain salt
  • 500 g (1 lb 2 oz) neymeen or kingfish, in 4 thick steaks about 2.5 cm deep

Allergens: Fish. Gluten (wheat) — only if your asafoetida is compounded with wheat flour, as most brands are (it arrives with M05).

Equipment: Unglazed clay pot (meen chatti), 20–22 cm. Substitute: any heavy non-reactive pan — stainless steel, enamelled cast iron, a kalchatti. You lose the microporous wall that returns a little of yesterday's curry to today's, and you lose about five minutes of residual cooking, so take the fish off the heat slightly later. Do not use bare iron or aluminium: kudampuli will pick up a metallic edge from both.

Method — tap a step to mark it done, tap a time to start a timer

  1. Soak the kudampuli in the warm water. It is ready when it has gone from brittle to the texture of a dried apricot and the water has coloured to weak tea, . Keep the soaking water.
  2. Heat the clay pot slowly over a low flame for before anything goes in — clay cracks on thermal shock, not on heat. Add 5 g of the coconut oil.
  3. Fry the shallots, ginger, garlic and green chilli with a pinch of the salt until the shallots have collapsed and gone gold at the edges with no white left anywhere in the pan, on a low-medium flame. This is where the curry gets its body, and it is the step people rush.
  4. Add the M05 fish masala and curry leaves and stir constantly for , until the dusty raw note lifts off the pan and what replaces it is rounder and warmer. If it looks like catching, a tablespoon of water rather than more oil.
  5. Pour in the 350 ml water and the kudampuli with its soaking liquid, add the rest of the salt, and simmer uncovered until the gravy has darkened and thickened enough to coat the back of a spoon thinly, . Taste it now: it should be aggressively sour and slightly too salty, because the fish will absorb both.
  6. Slide in the fish steaks in a single layer, spooning gravy over them. Do not stir again — shake the pot instead.
  7. Simmer at a bare tremble, where a bubble breaks the surface every second or two, until the flesh has turned from translucent to opaque and gives slightly when pressed with the back of a spoon rather than squashing, . Take it off while the very centre still looks a shade underdone.
  8. Finish off the heat with the remaining 5 g of coconut oil poured over the surface, and leave the pot uncovered for before you touch it. The clay carries on cooking the fish for after the flame is out.
Why this worksKudampuli's acids keep migrating into the fish for hours after cooking, firming its protein and softening connective tissue, while the gravy's soluble compounds and the fish's own trade places. Its acidity is smoky and rounded rather than sharp, so it integrates into the gravy instead of sitting on top of it — which is exactly why tamarind's brightness fades overnight and this deepens.
Sourcing note

Kudampuli is sold as kodampuli, "Malabar tamarind" or "gambooge" in every Kerala-facing shop and online everywhere. Rinse it: the commercial product is often smoke-cured to speed drying, which is why one bag tastes of clean fruit acid and the next of a bonfire. In the US: kingfish steaks at Indian and Caribbean fishmongers, or Spanish mackerel, wahoo or mahi-mahi. In the UK: kingfish or coley at Asian counters; huss and monkfish tail both work and hold together beautifully. In the Gulf: ask for chanad — it is the same fish. In Australia: Spanish mackerel is the exact species, and school mackerel or blue-eye trevalla are good stand-ins. Any firm, thick, non-flaking fish will make this curry; a soft white fish will disintegrate.

If you are watching…

Blood sugar: 7 g of net carbohydrate makes this one of the lowest-load main dishes in the book. What decides the meal is the rice: 150 g cooked matta (R015) adds about 45 g of net carbohydrate, and a 50 g serving of vanpayar (R053) alongside cuts the glycaemic response of that rice more than swapping the rice would.

Blood pressure: 300 mg is 15% of a 2,000 mg day. To go lower, drop the added salt to 2 g and lean harder on the kudampuli — sour and hot together mask a missing gram of salt better than anything else in this cuisine.

Cholesterol: 4 g of saturated fat, most of it from the 10 g of coconut oil. Sesame or groundnut oil takes it to about 2 g and the curry is still recognisably itself, though the raw finishing drizzle is where coconut oil earns its place.

Swap it

No neymeen → ayala or mathi. Oilier, stronger, and better value; cut the coconut oil to 5 g in total because the fish brings its own. Omega-3 per serving goes up.

No kudampuli → 15 g tamarind pulp. The curry becomes rounder and brighter and does not improve overnight, so eat it the day you make it.

No M05 → 8 g Kashmiri chilli powder, 4 g ground coriander, 2 g turmeric and a pinch of fenugreek. Slightly flatter; you lose the pepper and the roasted depth. (The fenugreek here is under 1 g across four servings and nowhere near the 10–25 g a day at which fenugreek has real glycaemic effects — but anyone taking insulin or a sulfonylurea should read the caution at M05 and in Chapter 9.)

No clay pot → see EQUIPMENT. The curry works; it will not archive.

Make ahead · store · freeze

Better on day two, and this is not a figure of speech. Fridge 3 days in a covered non-metal container. Freeze 2 months; the fish loses texture, the gravy does not, so freeze gravy alone if you can and poach fresh fish in it. Reheat to a bare tremble only, never a rolling boil.

Leftovers

Flake the fish off the bone into a thoran with 40 g grated coconut and a curry-leaf tempering. Or spoon the cold gravy — it will have set slightly — over hot kanji (R020), which is what a Kottayam household does with the last of the pot.

Troubleshooting

Curry tastes of raw chilli powder: step 4 was cut short. Simmer another 8–10 minutes; it will come round.

Fish fell apart: it was stirred, it went in before the gravy had thickened, or the fish was tired. Shake the pot, never stir it.

Thin and watery: not enough shallot reduction at step 3, or the gravy was not simmered down at step 5. Lift the fish out and reduce the gravy 4–5 minutes, then return it off the heat.

Metallic, hard-edged sourness: an aluminium or bare-iron pan. This is the one dish where the vessel genuinely matters.
