A vibrant, fast-cooking North Indian seafood dish where tender prawns are enveloped in a rich, tangy tomato sauce spiced with coarsely crushed coriander, chillies, and ajwain. Fresh ginger, green chillies, and a splash of lemon juice give it a sharp, aromatic finish.
Warm 100 g ghee or vegetable oil in a wok or kadhai set over medium heat. Tip in 160 g chopped onion and fry gently for about 5 minutes, stirring frequently, until deep golden-brown.
Stir in the garlic paste and cook for 15 seconds. Tip in the coarse spices and sauté for another 30 seconds until intensely fragrant.
Turn the heat up to high and slide in 750 g chopped tomato together with three-quarters of both the 40 g chopped fresh ginger and 36 g chopped green chilli, setting aside the remainder for garnish. Lower the flame to medium and simmer for around 5 minutes, allowing the masala to thicken until oil beads along the edges.
Slide in 750 g prawns and stir-fry for roughly 5 minutes until opaque, curled, and just cooked through. If too much liquid remains in the pan, crank the flame to high for 1 to 2 minutes to boil off the extra juices.
Season with salt to taste, then scatter over the finishing spices, 61.2 g lemon juice, 5.9 g chopped coriander leaf, and the reserved fresh ginger and green chilli. Toss well to combine and take off the heat to serve immediately.
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 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.
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 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.
Grind whole seeds finely in a spice grinder; use equal weight (1:1). Ensure it cooks through gently, as undercooked or burnt ground seeds become intensely bitter.
Crush dried leaves between your palms and add towards the end; use 50% of the weight. Gives the unmistakable maple-herb aroma without the sharp bitterness of the seeds.
