In a wide bowl, thoroughly combine 254 g plain yogurt, the spices for the yoghurt, and salt to taste.
Warm 125 g ghee in a heavy-bottomed pan over medium heat. Tip in the whole spices for the ghee and fry for roughly 1 minute until the cardamom begins to colour. Stir in 150 g onion, 3 g garlic, and 12 g ginger, cooking for about 2 minutes until the onions become soft and translucent.
Turn the heat up to high, add 1000 g chicken, and fry briskly for 4 minutes.
Take the pan off the heat and stir in the seasoned yoghurt mixture. Set the pan back on the heat, then mix in 20 g coriander leaf, 4 tablespoon mint, 72 g green chilli, the spices for the simmer, and 250 g water.
Place the lid on the pan and seal the rim completely with 150 g dough. Turn the heat down to low and leave to cook for 20 minutes, gently agitating the pan from time to time.
Break the seal and lift off the lid. Simmer gently for about 5 minutes, stirring thoroughly, until the sauce thickens and the chicken is fully tender. Adjust the seasoning with additional salt if needed.
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.
Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.
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.
Use 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.
Use about 30% of the weight of fresh mint. Rub between your palms to crush before stirring in; the flavour will be more intensely herbal and less bright.
Grate whole nutmeg finely on a microplane; use 80% to 100% of the weight. Freshly grated nutmeg has significantly more aromatic oils and a more vibrant aroma.
Use 100% to 120% of the weight. Mace is nutmeg's outer husk, providing almost identical warmth but with a lighter, slightly more delicate, floral edge.
