Method

  1. Boil 2100–2400 g unpeeled potato in a large pan of water for 20 minutes until tender. Drain, allow to cool, strip off the skins, and dice the flesh into 1 cm (½ in) pieces.
  2. Put the spices for the paste into a blender with 12.6 g roasted chana dal and a splash of water, then blitz until completely smooth.
  3. Heat 81 g vegetable oil in a deep, heavy frying pan or kadhai over medium heat. Tip in the tempering spices, 4.3 g urad dal, 4.2 g chana dal, and 1 g curry leaf, then fry for 1 minute until the mustard seeds crackle.
  4. Add 450 g chopped onion to the pan and cook for 5 minutes, stirring frequently, until golden.
  5. Stir in 12–18 g green chilli, 4.8 g ginger, 480 g tomato, the ground spices for the sauce, and salt to taste. Sauté for 1 to 2 minutes.
  6. Pour 250 g water into the pan and mix well. Lower the heat, cover with a lid, and simmer gently for 5 minutes.
  7. Remove the lid, fold in the blended spice paste along with the diced potatoes, and simmer uncovered for 5 minutes until thoroughly combined.
  8. Pour in 380 g coconut milk and simmer for 1 to 2 minutes before removing from the heat.

Don't have something?

Potato
  • Eggplant

    Use equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.

  • Paneer

    Use 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.

  • Dried chickpea

    Use 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

Onion
  • Shallot

    Use equal weight, finely sliced. Shallots soften and brown faster, giving a slightly sweeter and more delicate base to curries.

  • Cabbage

    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.

Green chilli
  • Chilli powder

    Use 10 to 15% of the weight (about 1/4 teaspoon per chilli); imparts dry pungent heat and reddens the dish without the grassy crunch.

  • Dried red chilli

    Use 1 dried pod per fresh green chilli; snap in half and temper in hot oil for a deeper, toastier heat.

Ginger
  • Fresh ginger

    Use equal weight; scrape off the skin and grate or finely julienne according to the recipe.

  • Ginger paste

    Use equal weight; stir straight into the sizzling aromatics, taking care as the extra moisture may spit.

  • Ground ginger

    Use 15 to 20% of the weight; add alongside ground spices, noting it imparts warm, dry heat rather than zesty freshness.

Tomato
  • Tomato purée

    Use 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.

  • Plain yogurt

    Use 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

Ground turmeric
  • Ground ginger

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

  • Saffron

    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.

Coconut milk
  • Single cream

    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.

  • Cashew paste

    Whisk 1 part cashew paste with 2 parts water to match the consistency, then use equal weight. Provides a thick, velvety body without coconut flavour.

  • Whole milk

    Use equal weight, but reduce other cooking liquids by 20% to compensate for the lower viscosity. The curry will be lighter and lack sweetness.

Poppy seed
  • Cashew nut

    Use equal weight. Soak in warm water for 20 minutes and grind to a smooth paste; produces an even creamier, slightly richer gravy than poppy seeds.

  • White sesame seed

    Use equal weight. Soak and grind finely; provides similar thickening and body with a slightly nuttier, faintly bitter edge.

  • Almond

    Use equal weight. Blanch, peel, and grind finely with a splash of water; lends a velvety body and gentle sweetness to gravies.

Dried red chilli
  • Dried kashmiri chilli

    Use equal weight whole. Fry in hot oil or ghee as tempered spice; gives a richer red colour with slightly milder heat.

  • Red chilli powder

    Use 50% to 70% of the weight. Stir into the oil with ground spices; distributes heat evenly throughout the dish without whole chilli skins.

Chana dal
  • Yellow split peas

    Use 100% of the weight. Soak for at least 1 hour; takes about 10 minutes longer to cook through and has a marginally earthier flavour.

  • Pigeon peas

    Use 100% of the weight. Reduces cooking time by about 10 minutes and breaks down softer, giving a smoother consistency rather than distinct grains.

  • Black gram

    For tempering or tadka only: use 70% of the weight. Browns faster in hot oil, providing a nutty, crunchy bite.

Coriander seeds
  • Ground coriander

    Use 75% of the weight; stir in along with wet masala or tomato purée rather than frying in hot oil, as the fine powder burns instantly.

  • Cumin seed

    Use 50% of the weight for tempering in hot oil. Lacks the floral, sweet citrus flavour of coriander, introducing warm, pungent earthiness instead.

  • Fennel seed

    Use 50% of the weight in tempering; provides pleasant aromatic sweetness, though noticeably aniseedy rather than citrusy.

Fennel seed
  • Aniseed

    Use 75% of the weight. Fry in hot oil or ghee; has a sharper, more pronounced liquorice flavour, so use a lighter hand.

  • Ground fennel seed

    Use 60% of the weight. Stir into the sauce with ground masalas; provides identical sweet aniseed flavour without whole seed crunch.

  • Star anise

    Use one point (single carpel) per 1 g of fennel seeds. Simmer in gravies and remove before serving; gives a deeper, woodier liquorice aroma.

Cassia bark
  • Ceylon cinnamon

    True cinnamon: thinner, papery quills, milder and sweeter. Use about 1.5 times the weight, and taste.

  • Ground cinnamon (cassia)

    Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.

  • Cassia buds

    Use 60-70% of the weight; stronger and more peppery, so taste before adding more.

Vegetable oil
  • Peanut oil

    Use 1:1 by weight. Handles high-heat frying identically and introduces a very subtle, pleasant nuttiness.

  • Ghee

    Use 1:1 by weight. Yields a much richer, authentic aroma and a glossy, heavier mouthfeel.

  • Mustard oil

    Use 1:1 by weight. Heat until smoking, then cool slightly before cooking to temper its intensely pungent, sharp mustard kick.

Mustard seed
  • Black mustard seed

    Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.

  • Yellow mustard seeds

    Use the same weight. They are milder and larger; fry a few seconds longer until they pop. The finished dish will have less pungency.

  • Ground mustard seed

    Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.

Cumin seed
  • Ground cumin

    Use 70% of the weight; add with ground spices or sauce bases rather than hot oil tempering, where it scorches quickly and turns bitter.

  • Black cumin seeds

    Use equal weight for oil tempering. Delivers an earthy profile with an additional musky, smoky, and slightly bitter edge.

  • Fennel seed

    Use 60% of the weight for tempering; offers comparable warm aroma, but leans sweet and liquorice-like rather than savoury and earthy.

Urad dal
  • Whole black gram

    Use equal weight. Needs longer soaking and cooking; the dark skins impart an earthy flavour and greyish-black hue unless thoroughly rubbed off.

  • Chana dal

    Use equal weight when tempering (tadka). Provides a comparable nutty, crunchy texture in hot oil, though grains are slightly larger.

  • Split mung beans

    Use equal weight for batters or dals. Ferments and cooks faster, producing a lighter, less sticky, and less viscous consistency.

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.
