Method

  1. Dry-fry 30–40 g baby onion, quartered, in a dry pan over medium heat for 2–3 minutes, keeping them moving.
  2. Add 80 g coconut and fry for 4–5 minutes until it turns light brown. Take the pan off the heat and let it cool.
  3. Put the cooled onion and coconut in a blender with the theeyal paste spices (1.9 g fenugreek seed, 1.4 g black peppercorn, 2.6 g kashmiri chilli powder, 5.4 g ground coriander) and 79.5 g water. Blend to a smooth, fine paste and leave it in the blender.
  4. Heat 40.5 g coconut oil in a saucepan over medium heat. Add 500 g baby onion, peeled and halved if large, and fry for 7–8 minutes until the edges begin to colour. Lift the onions out and keep them aside.
  5. Add the whole spices for the tempering to the hot oil, then add 2–2.5 g curry leaf and 2 g green bird’s eye chilli, slit. Let them crackle.
  6. Add the theeyal paste and cook for 1 minute, stirring.
  7. Pour in 348 g water and add salt to taste, 27 g light brown soft sugar and the fried baby onion. Simmer over low heat for 3–4 minutes, stirring well.
  8. Stir in 54 g tamarind paste and simmer for 2 minutes more.
  9. Scatter over chopped coriander leaf to taste and serve.

Don't have something?

Coconut oil
  • Vegetable oil

    Use the same weight; it is neutral and will not add coconut aroma.

  • Groundnut oil

    Use the same weight; mild and good for frying, but no coconut flavour.

  • Ghee

    Use the same weight for richness; it adds a dairy aroma and is not vegan.

Baby onion
  • Baby pearl onion

    Use the same weight; peel and leave whole. Almost identical, though pearl onions can be slightly sweeter.

  • Shallot

    Use the same weight; halve if large. Sweeter and cooks 2 minutes faster, so add later.

  • Onion

    Use the same weight, cut into small wedges. Stronger and sharper; cook 2–3 minutes longer.

Black mustard seed
  • Mustard seeds

    Use equal weight. Pop in hot fat until they crackle and turn greyish; yields an almost identical nutty, pungent finish.

  • Yellow mustard seeds

    Use equal weight. Fry over medium heat; delivers a milder, sweeter pop and turns bitter quickly if the oil is excessively hot.

Curry leaf
  • Bay leaf

    Fry 1 bay leaf for every 5 curry leaves in hot oil; imparts a warm, woodsy background note, but misses the citrus-sulphury punch entirely.

  • Lime juice

    Add a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.

Green bird's eye chilli
  • Bird's eye green chilli

    Use the same weight; heat and flavour are very close.

  • Green chilli

    Use 1.5 to 2 times the weight; deseed for less heat. Larger chillies are more watery.

  • Fresh green chilli

    Use 1.5 to 2 times the weight; chop finely and adjust heat by tasting.

Dried round red chilli
Water
  • Stock

    Use the same weight in savoury dishes; it adds body, so adjust salt.

  • Milk

    Use the same weight only in doughs or creamy dishes; it makes the result richer.

  • Coconut water

    Use the same weight in curries or rice; it adds sweetness and a faint coconut taste.

Brown sugar
  • Demerara sugar

    Use the same weight; it is drier and slightly less molasses-rich, so taste and add a little more if needed.

  • Jaggery

    Use the same weight; it is stronger and more mineral, so dissolve it first and reduce any other sweetener.

  • Granulated sugar

    Use the same weight; it is less moist and less dark. Add 5 g cane molasses per 100 g if you have it.

Tamarind paste
  • Tamarind pulp

    Use 120–150% of the weight and strain; pulp is less concentrated, so simmer a little longer to thicken.

  • Tamarind extract

    Use 150–200% of the weight and reduce gently; extract is already diluted.

  • Lime juice

    Use 60–70% of the weight with a pinch of jaggery; sharper, so add near the end off the heat.

Coriander leaf
  • Coriander

    Use equal weight finely chopped; this is the exact same fresh herb.

  • Mint

    Use half the weight finely chopped; provides vibrant green freshness, though the flavour profile becomes noticeably cooler and sharper.

Coconut
  • Fresh coconut

    Use equal weight freshly grated or diced. Delivers the identical sweet, milky taste and juicy texture.

  • Desiccated coconut

    Use 60% of the weight and soak in hot water or milk for 15 minutes before using. The finished dish will be slightly sweeter and less fibrous.

  • Dried coconut

    Finely grate and use 50% of the weight, soaked in hot water for 20 minutes. Yields a firmer chew and a denser, oilier coconut aroma.

Fenugreek seed
  • Mustard seed

    Use 50% of the weight, crush or grind. Sharper heat and less maple-bitter; fry briefly in oil before adding.

  • Caraway seeds

    Use the same weight, crush lightly. Similar bitter-seed note but more aniseed; reduce other sweet spices slightly.

  • Ajwain seeds

    Use 25–30% of the weight, crush. Much stronger thyme-like flavour; do not overdo.

Black peppercorn
  • Coarsely ground black pepper

    Use 75% of the weight. Add midway through simmering; spreads heat evenly through the dish instead of delivering isolated bursts.

  • Ground black pepper

    Use 50% of the weight. Stir in near the end of cooking; significantly darkens light gravies and provides an immediate, sharp bite.

Kashmiri chilli powder
  • Dried kashmiri chilli

    Grind deseeded dried pods to an equal weight of powder; gives identical vivid red colour and gentle warmth.

  • Red chilli powder

    Use 25% of the weight mixed with sweet paprika for colour; straight red chilli powder is substantially hotter and will make the dish fiery.

  • Chilli powder

    Use one-third of the weight; the sauce will be less intensely red and notably sharper in heat.

Ground coriander
  • Coriander seeds

    Dry-roast lightly in a pan and grind to a fine powder; use equal weight (1:1). Offers a noticeably fresher, brighter citrus note.

  • Ground cumin

    Use 50% to 75% of the weight. Lacks the floral, citrusy profile of coriander and turns the gravy heavier, earthier, and darker.

  • Garam masala

    Use 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.
