Warm 228 g vegetable oil or ghee in a wide, heavy-bottomed pot set over the lowest heat.
In a large bowl, thoroughly combine 1000 g lamb cut into pieces, 1000 g thinly sliced onion, 259 g whisked yogurt, 3 g garlic, the whole spices for the stew, and salt to taste.
Transfer the mixture into the warm pot. Fit with a tight lid and let it simmer gently for around 2 hours, until the meat becomes thoroughly tender.
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 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.
Allspice berries
Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.
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.
