DifficultyEasy, but it needs your full attention for the last 5 minutes
The re-engineeringOil down from about 45 g to 12 g. The dish still ends up glossy and dark, because the browning comes from the prawns' own moisture cooking off against a hot pan and from the coconut slivers toasting in their own fat — not from added oil.

Ularthiyathu means dry-roasted down, and it is the technique behind Kerala's most famous meat dish. Applied to prawns it becomes a fifteen-minute pan dish: the gravy vanishes, the pieces darken, the coconut slivers go gold, and what is left clings to the prawns instead of pooling under them. It is a toddy-shop dish and it is meant to be eaten with your fingers off a banana leaf.

Before you start: This dish moves fast and there is no pause once the prawns go in. Have the coconut slivered, the aromatics chopped, the powders weighed, and the curry leaves stripped before you light the flame.

Ingredients — tap to tick off

  • 500 g (1 lb 2 oz) raw prawns, peeled and deveined
  • 10 g (1½ tbsp) M05 fish masala
  • 3 g (½ tsp) black pepper, coarsely crushed
  • 2 g (⅓ tsp) M07 salt, or plain salt
  • 12 g (2½ tsp) coconut oil, divided: 9 g and 3 g
  • 100 g (about 10) shallots, thinly sliced
  • 15 g (a 3 cm piece) ginger, finely chopped
  • 10 g (about 3 cloves) garlic, finely chopped
  • 3 green chillies (about 15 g), slit
  • 40 g (about ½ cup) fresh coconut, cut into thin slivers (thenga kothu)
  • 3 g (1 sprig) curry leaves

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

Equipment: Wide heavy pan or cheena chatti, 26–28 cm. Substitute: any wide pan. A narrow one steams the prawns instead of roasting them, which is the one way to fail at this.

  1. Toss the prawns with the M05, pepper and salt and leave while you prepare everything else.
  2. Heat the pan properly, then add 9 g of the oil and the coconut slivers, and toast over a medium flame, stirring, until they turn from white to pale gold at the edges, . Lift them out and set aside; they will finish later and would burn otherwise.
  3. Add the shallots, ginger, garlic and green chilli to the same pan and cook over a medium flame until the shallots are soft and browning at the edges, .
  4. Add the marinated prawns in a single layer and leave them undisturbed 60–90 seconds to take colour before you move anything. Then stir and cook until they have gone pink and opaque and curled loosely, total.
  5. Raise the flame, return the coconut slivers, and roast everything together, stirring almost constantly, until the pan is dry, the masala clings to the prawns in a dark coating, and the slivers are deep gold, . If liquid runs when you tilt the pan, keep going.
  6. Finish off the heat with the remaining 3 g of oil and the curry leaves, which will crackle in the residual heat. Serve within a few minutes; this dish does not improve standing.
Why this worksThe prawns release water as they set, and on a wide pan it evaporates faster than it accumulates, so the surface stays hot enough for the masala to brown against the prawn protein rather than simmer into a sauce. The coconut slivers are toasted separately and returned late for the reason a nut goes in at the end: their fat browns fast and would turn bitter.
Sourcing note

As R032 for prawns. On the coconut slivers: these are cut from the kernel with a knife rather than grated, into pieces about the size of a matchstick, and they are structural — they toast, they crunch, and they are half the reason this dish is worth making. Abroad: if you have a whole coconut, cut them yourself; frozen coconut chunks in South Asian and Caribbean freezers can be slivered from frozen. Frozen grated coconut will not do it — it burns before it toasts. Dried coconut chips, unsweetened, are the honest fallback and want to go in 2 minutes later than the recipe says.

If you are watching…

Blood sugar: 6 g of net carbohydrate. A dry roast like this is a good protein anchor for a plate where the rice is the variable.

Blood pressure: 300 mg, and about half of it is the prawns themselves. With no added salt at all it lands near 210 mg, and the pepper and green chilli carry it.

Cholesterol: 6 g of saturated fat, split roughly evenly between the 12 g of coconut oil and the 40 g of coconut slivers. Sesame oil takes it to about 4.5 g; halving the slivers to 20 g takes it to about 4 g and costs the dish its texture, which is a poor trade.

Swap it

Prawns → 500 g squid rings, 4–5 minutes at step 4 (see R037 for the timing rule), or 500 g diced firm fish, handled gently. Or 400 g mussel meat. (Allergen: this swap introduces fish, molluscs.)

No coconut slivers → 30 g desiccated coconut chips added at step 5. Less crunch, more even browning.

Add 100 g diced tomato at step 3 → wetter, more of a roast than an ularthiyathu, and 5 more minutes to dry out. A common household version.

Coconut oil → sesame or groundnut. Saturated fat falls about 1.5 g per serving; the finishing 3 g is where coconut oil is worth keeping. (Allergen: this swap introduces peanuts, sesame.)

Scale it

Eight servings will not roast dry in one domestic pan. Cook in two batches and combine at step 5, or accept a wetter dish.

Make ahead · store · freeze

Best within ten minutes of cooking. Fridge 2 days. Freeze 1 month, though the prawns become noticeably firmer. Reheat dry in a hot pan for 2–3 minutes; a microwave turns prawns to rubber.

Leftovers

Fold cold into a cabbage thoran, or into rice with a squeeze of lime, or roll into a wrap with raw onion and yoghurt. It is also excellent stirred through R020 kanji.

Troubleshooting

Prawns rubbery: overcooked, and it happens between step 4 and step 5. Take them out after step 4 and return them for the last 90 seconds if you are unsure.

Watery and pale: pan too small, flame too low, or prawns still wet from thawing. Pat them dry and use a wider pan.

Coconut slivers black and bitter: they stayed in through the whole cook, or the flame was too high at step 2. Out after 3 minutes, back in at the end.

Masala tastes raw: the prawns went in before the shallots were properly cooked at step 3.
