Warm 60 g vegetable oil or ghee in a heavy, wide pan set over medium heat. Fry 450 g onion for 5 to 7 minutes until richly browned.
Stir in 0.5 teaspoon ground turmeric, 2.5 g ginger and 1 teaspoon ground garlic, cooking for 30 seconds. Tip in 1 teaspoon ground aniseed, the toasting spice and 120 g dried coconut, stirring constantly for 1 to 2 minutes until fragrant.
Add the sauce spices, 5 cardamom pods, 183 g plain yogurt, salt to taste and 500 ml water. Simmer gently over low heat for 5 minutes. If you prefer a completely smooth gravy, allow it to cool slightly, blitz in a blender for 30 seconds, and thin with up to 125 ml water if it becomes overly thick.
Pulse 350 g lamb in a food processor until finely textured. Transfer to a pan over low heat to drive off residual moisture, preventing the meatballs from falling apart later. Beat 1 egg, incorporate thoroughly into the warm mince, and roll the mixture into walnut-sized balls.
Heat the remaining 168 g vegetable oil or ghee in a frying pan over medium heat. Fry the meatballs in batches for 5 to 8 minutes, turning until evenly browned, then lift out with a slotted spoon onto paper towels to drain.
Arrange the meatballs in a shallow serving dish and ladle over the piping-hot sauce until they are at least half covered. Serve hot alongside rice or flatbreads.
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.
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 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 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 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.
For binding, use about 10 g chickpea flour mixed with 20 ml water per egg and rest for 10 minutes. Denser and nuttier; not suitable for baking or coating in the same way.
