Preheat the oven to 190°C (375°F). Brush a 20 cm (8-inch) round baking tin with a little extra oil or ghee and line the interior with baking paper.
Warm 47.2 g ghee or vegetable oil in a large, heavy pan over medium-low heat. Fry 2 tablespoon slivered almonds for 30 seconds until pale gold, then lift them out with a slotted spoon. Toss in 50 g chopped raisins, sizzle for 30 seconds, and transfer them out of the pan.
Drop 60 g sliced onion into the remaining oil and fry for 5 to 7 minutes until richly browned. Scoop onto paper towels to drain, then crumble coarsely.
Add 1000 g ground lamb and salt to taste to the pan. Cook over medium heat for roughly 10 minutes until all liquid cooks off, then stir-fry the meat for 1 minute. Pour in 1 litre of water, bring to a boil, then turn the heat down and simmer uncovered for 30 minutes until the mince is tender and no liquid remains.
Stir together the fried almonds, raisins, crushed onions, 12 g chopped ginger, 60–90 g chopped green chilli, and 1 g chopped coriander leaf in a bowl. In a second bowl, lightly beat 4 eggs with 15.3 g lime juice.
Spread half of the cooked meat across the base of the lined tin. Drizzle over half of the 127 g single cream, scatter half of the nut and herb mixture, and pour over half of the beaten egg mixture, pressing down lightly to level. Layer the remaining meat, cream, nut mixture, and egg on top in the exact same order.
Bake for about 30 minutes until the bake has fully set and feels firm. Leave to cool down, then portion into wedges.
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 minced chicken (preferably dark thigh meat) at 100% of the weight. Halve the browning and simmering time; add an extra tablespoon of ghee or oil as chicken is much leaner than lamb.
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.
