A rich Bengali-style mutton curry where bone-in goat meat is slow-cooked with potatoes, onions, yogurt, and warm spices until the masala clings to every piece. Deep flavor, gentle heat, and a thick, glossy finish make it perfect with rice or luchi.

Add the remaining mustard oil to the cooker. When it is hot and the raw smell fades, add bay leaf, cinnamon, green cardamom, cloves, and cumin seeds. Let them sizzle for 20 to 30 seconds.
TIPLet mustard oil heat properly before adding spices for a smoother, less sharp taste. - saute · ~15 min

Bhuno the mutton with the masala.
Add the marinated mutton to the cooker and cook on medium-high heat, stirring often, until the meat changes color and the masala thickens and starts leaving the sides, 10 to 12 minutes.
TIPThis slow bhuno stage builds the deep color and robust taste that define a good kassa. - pressure cook · ~25 min
Pressure cook the mutton and potatoes.
Return the fried potatoes to the cooker and pour in the hot water. Mix well, cover, and pressure cook on medium heat for 20 to 25 minutes, or until the mutton is tender.
- simmer · ~10 min
Reduce the gravy to a thick finish.
Release the pressure, open the cooker, and simmer uncovered until the gravy becomes thick and coats the meat and potatoes well, about 8 to 10 minutes. Stir in the garam masala and ghee in the last minute.
TIPKassa should be thick and clingy, not runny, so reduce the gravy until it shines. - serve

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the potatoes dry before frying so they blister and hold shape in the gravy.
- 2Whisk the yogurt well before marinating to help it coat the mutton evenly and prevent splitting.
- 3Do not rush the onion stage; deep golden onions give kassa its signature dark, rich base.
- 4During bhuno, scrape the bottom often so the masala browns without catching and turning bitter.
- 5Use hot water, not cold, when pressure cooking so the meat keeps cooking steadily and stays tender.
- 6If the gravy thickens before the mutton softens, add a small splash of hot water and continue cooking.
- 7Rest the curry for 10 to 15 minutes before serving so the oil settles and the masala clings better.
Adapt it for your goals.
Low-oil
Use less mustard oil and skip frying the potatoes deeply; the curry will be lighter while still keeping the Bengali spice profile.
extra spicyExtra-spicy
Add more slit green chilies or a little extra red chili powder for a hotter, sharper kassa suited to spice lovers.
no pressure cookerNo-pressure-cooker
Cook in a heavy pot on low heat until the goat turns tender; it takes longer but develops an equally deep masala.
bonelessBoneless
Use boneless mutton for easier serving, though bone-in pieces give the gravy a richer, fuller taste.
