A comforting North Indian curry featuring tender chunks of lamb and potatoes simmered in a spiced, yoghurt-based sauce. The gravy is rich, gently tangy, and deeply aromatic.
Ground spices for the sauce
5 gFried with the ginger, garlic, and yoghurt (step 3)
Warm 125 g ghee in a large, heavy pan set over medium heat. Fry 100 g sliced onion for 5 to 7 minutes until deep golden brown, then scoop out with a slotted spoon and set aside.
Drop 100 g finely chopped onion into the remaining ghee and cook for 3 to 4 minutes until pale gold.
Add 30–36 g ground garlic, 12 g peeled and ground ginger, the ground spices for the sauce, and 2 tablespoons of the 388 g whisked yogurt. Cook for around 5 minutes, stirring steadily, until the spice paste turns brown and ghee releases at the edges.
Tumble in 500 g lamb pieces and season with salt to taste. Sauté for roughly 5 minutes, stirring occasionally, until all released liquid boils away and the meat takes on colour.
Pour in the rest of the whisked yogurt, add the garam masala, and stir in 500 ml water. Simmer gently for approximately 30 minutes, or until the lamb is nearly tender.
Add 1000 g quartered potatoes, pouring in a little extra water if the gravy has reduced too far. Cover the pan and simmer for an additional 30 minutes until both the potatoes and meat are tender throughout.
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.
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 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.
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 50% of the weight mixed with equal parts ground coriander and a pinch of ground cinnamon, ground cloves, and ground green cardamom. Sprinkle near the end for a warming finish.
