A pungent, tangy North Indian specialty infused with robust pickling spices, mustard seeds, fenugreek, nigella seeds, and fresh green chillies.
Heat mustard oil to smoking, cool slightly, then crackle the mustard, fennel, and nigella seeds.
Add the onions and cook until golden, then stir in the ginger-garlic paste until fragrant.
Add the chicken with salt and sear on all sides until lightly browned.
Whisk the Kashmiri chili powder into the yogurt, stir into the pan, cover, and simmer 25-30 minutes until the chicken is tender.
Uncover and reduce until the gravy clings to the chicken; serve with roti or jeera rice.
