Oil your hands and knife to handle the sticky latex, then peel 1 jackfruit, discard the central core and seeds, and chop the flesh into 2.5 cm (1-inch) pieces.
Bring a large pan of salted water (about 750 ml to 1 litre) to a boil, submerge the jackfruit, cover, and simmer for 10–15 minutes until tender. Drain thoroughly and transfer to a bowl.
Toss the warm jackfruit with 5.1 g desiccated coconut, 100 g of the 600 g sliced onion, 2 g sliced ginger, 36 g chopped green chilli, and the jackfruit spice.
Warm about 30 ml of the 40.5 g vegetable oil in a skillet over medium-low heat. Add the tempering seeds and 100 g of the sliced onion, frying for around 5 minutes until golden brown. Stir this into the jackfruit bowl and sauté the mixture in the pan for 2–3 minutes, then set aside.
Soak 400 g basmati rice in water for 20 minutes, then drain thoroughly. Preheat the oven to 140°C (275°F).
Heat the remaining vegetable oil in a deep, heavy, ovenproof pot over medium heat. Fry the remaining 400 g sliced onion for about 5 minutes until richly browned, then lift out and reserve.
In the same hot oil, fry the rice spices and 2.5–3.8 g curry leaf for 1 minute. Add 36 g slit green chillies and cook gently for 1–2 minutes, then stir in the drained rice and fry for 3–5 minutes until the grains turn translucent.
Combine 507 g coconut milk with 500 ml boiling water and pour over the rice—the liquid should rise roughly 5 cm above the surface, so add extra water if needed. Stir in half the ghee (4.4 g of the 8.8 g total), 1 diced carrot, 50 g peas, and salt to taste. Cover and simmer for 10 minutes until half-cooked, then take off the heat.
Scoop out half of the par-cooked rice. Spread the seasoned jackfruit evenly over the bottom layer, then top with the reserved rice. Drizzle over 1 lime juice and the remaining 4.4 g ghee, then scatter the reserved fried onions, the finishing cardamom, and 100 g chopped coriander leaf over the top.
Cover the pot tightly with a lid or foil and bake in the oven at 140°C (275°F) for 20–25 minutes until the rice is fully tender and fragrant.
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 the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.
Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
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.
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 equal weight; simmer gently over low heat to prevent curdling. Imparts a comparable rich texture, though it adds dairy richness without any coconut fragrance.
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 the same weight; peel and cut as for carrot. It is less sweet and slightly peppery, so add a pinch of sugar and expect a softer, more earthy result.
