A comforting South Indian curry featuring tender potatoes cooked in an aromatic coconut and green chilli paste, finished with whisked yoghurt. The dish has a rich, mildly spiced flavour balanced by pleasant tartness.
Place 12.6 g chana dal in a bowl of water, soak for 20 minutes, then drain thoroughly.
Warm a small, heavy-based dry pan over medium heat, add the fenugreek for toasting, and stir-fry for 1 to 2 minutes until roasted and fragrant.
Tip the toasted fenugreek into a small blender. Add the drained chana dal, the mustard seeds for the spice paste, 24–30 g green chilli, 2 g coriander leaf, 4.8 g ginger, 100 g fresh coconut, and 60 ml water, then blend into a smooth paste.
Bring 375 ml water to a boil in a large, heavy saucepan. Add 600–900 g potato, the turmeric for the potatoes, and salt to taste. Cover, adjust the heat to medium, and simmer for 10 to 12 minutes until the potatoes are tender.
Mix the blended spice paste into the potatoes and simmer for 1 to 2 minutes.
Pour in 621 g yogurt and warm through over gentle heat for 1 to 2 minutes, stirring steadily to stop the sauce from splitting.
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.
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.
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.
Use 50% to 60% of the weight, soaked in equal parts warm water for 15 minutes before grinding. Works well for chutneys, though texture is slightly finer and sweeter.
Use 1.2 times the weight in curries. Adds creamy richness and authentic flavour, but makes gravies smoother and eliminates the grated, chewy mouthfeel.
