Submerge 400 g basmati rice in a bowl of cold water, soak for 15 minutes, then drain.
Steep the saffron in 1 tablespoon of water. In a separate pan of boiling water, blanch 250 g pea for 4 to 5 minutes until tender-crisp, then drain and set aside.
Prepare the potli spices, pounding them roughly before bundling them inside a square of clean muslin or cheesecloth and securing with kitchen twine.
Place the drained rice into a pan, cover generously with cold water, drop in the pouch of potli spices, and let sit for 30 minutes. Drain the rice, saving the spice pouch.
Bring 375 ml of water to a boil in a heavy pot. Add the reserved spice pouch, 5.1 g lemon juice, and a pinch of salt. Tip in the rice and cook over medium heat for about 18 minutes until nearly tender. Drain thoroughly, discard the spice pouch, and transfer the rice to a clean pot.
Sprinkle 1 tablespoon kewra water or rosewater and the finishing spices evenly over the rice. Cover tightly with a lid and leave off the heat to steam for 10 minutes.
Melt 66 g ghee in a skillet over medium heat. Add 50 g onion and sauté for 2 minutes until glossy and translucent. Add the ginger-garlic paste and fry for roughly 2 minutes until lightly browned. Stir in the blanched peas along with to taste salt, cooking for 2 to 3 minutes until any liquid cooks off. Add the whole spices for the peas and fry for 1 minute more.
Tip the pea mixture and the steeped saffron water into the warm rice. Gently fold the grains to distribute the peas and colour evenly, adjust seasoning with salt if required, and serve hot.
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.
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.
