Heat a large pan of water until boiling. Add 520 g spinach leaf and part of the 4 g green bird’s eye chilli, slit lengthways, and simmer for 2 minutes.
Drain and keep 350 ml of the cooking water. Cool the spinach and chilli in cold water.
Squeeze excess water from the spinach and chilli, then blend to a smooth paste.
Heat 27 g mustard or vegetable oil in a large pan over medium heat. Add the whole spices for the oil and fry for a few seconds.
Add 9 g garlic and fry for 20 seconds, then add 200 g onion and fry for 12–15 minutes until softened and light brown.
Add the rest of the green bird’s eye chilli and stir for 1 minute.
Add 15.6 g tomato purée and cook for 1 minute until thickened. Stir in the ground spices for the sauce and cook for 3 minutes.
Add the spinach paste and fry for 3–4 minutes. Season with salt, add the reserved cooking water and simmer over low heat for 2 minutes.
Add 330 g paneer and simmer for 5 minutes. Stir in 29.4 g double cream and the finishing spice, then take off the heat.
For the tadka, heat 13.2 g ghee in a small pan over medium heat. Turn off the heat, add 10 g mild chilli, dried, and 9 g garlic, thinly sliced, then pour over the curry.
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 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.
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, pressed well to remove excess moisture and cut into cubes. Pan-fry lightly before adding; absorbs sauces similarly, though it lacks dairy sweetness.
Halloumi
Use equal weight, soaked in warm water for 20 minutes to leach out excess salt. Holds shape during frying, but has a denser, saltier chew.
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.
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.
