Drop 1000 g peas into boiling water and cook until tender, roughly 5 minutes. Drain thoroughly, let cool, and chop coarsely.
Boil 1 potato until completely tender through the centre, about 10 minutes. Drain, cool, peel off the skin, and grate.
Warm 100 g ghee in a wok over medium heat. Tip in the tempering seeds and let them sizzle for 1 to 2 minutes until crackling. Stir in the ground spices for the peas with a pinch of salt, then add the chopped peas. Cook until all pan moisture dries up, mix in the grated potato, and stir-fry for 3 minutes before taking off the heat to cool.
To the cooled vegetable base, add 12 g ginger, 18 g green chilli, the patty spices, 20 g cornflour, and 30 g breadcrumbs. Season with salt, blend thoroughly into a uniform mixture, and shape into 16 equal portions.
In a small bowl, combine 25 g grated paneer, 25 g grated khoya, 1 teaspoon chopped coriander, 1 g fresh ginger, 1.6 g green chilli, 1 teaspoon raisin, the filling spice, and salt to taste.
Flatten a portion of the pea mixture in your palm, place a spoonful of filling in the middle, and wrap the edges over to seal completely. Gently press flat into a smooth disc, repeating with the remaining portions.
Heat a shallow layer of ghee in a non-stick frying pan over low heat. Fry the patties in batches for 8 to 10 minutes, flipping occasionally until both sides form a rich, crisp golden crust. Remove from the pan, dust with chaat masala to taste, and serve immediately.
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.
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.
For coating and frying, use the same weight; it gives a crisper, slightly gritty crust. For thickening, use 1.5 times the weight and simmer a little longer.
Use about 30% of the weight of fresh mint. Rub between your palms to crush before stirring in; the flavour will be more intensely herbal and less bright.
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 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.
