Steep the saffron infusion in 5.1 g milk in a small cup and set aside.
Add the whole spices for the paste to a blender along with 10 g fresh ginger, 2 cardamom pods, and a splash of water if needed, then process to a smooth paste.
Warm 40.5 g vegetable oil in a large, heavy pan set over medium heat. Stir in 600 g chopped onion and fry for 8 to 10 minutes until pale golden.
Lower the heat, add the prepared spice paste, and gently cook for 2 to 3 minutes.
Tip in 750 g skinless, boneless chicken and stir-fry for 5 minutes until every piece is evenly coated in the paste.
Pour in 750 ml hot water and raise the heat to bring the liquid to a boil. Turn the heat down and simmer uncovered for roughly 30 minutes, or until the chicken is tender and thoroughly cooked.
Drizzle in the soaked saffron infusion along with its milk and season to taste with salt. Put a lid on the pan and leave to steam over very low heat for 2 to 3 minutes.
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 20% to 25% of the weight (1 g for every 4 to 5 g fresh). Stir into the gravy; adds peppery heat and warmth, though it misses the crisp, zesty kick of raw root.
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.
