Nadan Mutton Chops
Slow-cooked mutton ribs in a spicy, thick onion-tomato masala.
About this dish
Nadan Mutton Chops is a quintessential 'touchings' (appetizer) or side dish found in the upscale toddy shops and Christian households of Central Kerala. Unlike thin gravies, this is a 'peralan' style dish—where the thick masala tightly coats the rib chops. The use of crushed peppercorns and vinegar provides a sharp, spicy kick that cuts through the richness of the mutton fat.
Ingredients
The Meat and Marinade
- 750g Mutton rib chops, trimmed
- 1 tbsp Ginger-garlic paste
- 1 tsp Turmeric powder
- 1 tbsp Black peppercorns, coarsely crushed
- 1 tbsp Coconut vinegar or white vinegar
- 1 tsp Salt
The Masala Base
- 3 large Red onions, thinly sliced
- 2 medium Tomatoes, finely chopped
- 3-4 Green chilies, slit
- 2 sprigs Curry leaves
- 2 tbsp Kashmiri chili powder
- 1.5 tbsp Coriander powder
- 1 tsp Garam masala (Kerala style)
- 3 tbsp Coconut oil
Method
- 1
Marinate the Ribs
Rub the mutton chops thoroughly with ginger-garlic paste, turmeric, crushed pepper, vinegar, and salt. The vinegar acts as a natural tenderizer for the tough rib meat. Let this marinate for at least 30 minutes, or overnight in the fridge for best results.

Pressure Cook the Meat
Place the marinated mutton in a pressure cooker with 1/2 cup of water. Cook for 4-5 whistles on medium heat (about 15-18 minutes) until the meat is 80% cooked and tender but not falling off the bone. Reserve the leftover cooking liquid (stock).

Sauté the Aromatics
Heat coconut oil in a heavy-bottomed pan or uruli. Add the sliced onions and a pinch of salt. Sauté on medium heat for 10-12 minutes until the onions turn a deep golden brown, almost caramelized. This 'browning' is the foundation of the dark masala color.

Build the Spice Profile
Lower the heat and add the green chilies, curry leaves, chili powder, and coriander powder. Sauté the dry spices for 2 minutes, splashing a little water if they start to stick, until the raw aroma disappears and the oil starts to separate.

Incorporate Tomatoes
Add the chopped tomatoes and cook until they turn mushy and blend into the onion base. Use the back of your spoon to mash the tomatoes, creating a thick, uniform paste that will eventually coat the chops.

Combine Meat and Masala
Add the par-boiled mutton chops along with the reserved stock into the pan. Stir well to coat every piece of meat with the masala. Increase the heat to medium-high to reduce the liquid.

The Slow Reduction
Continue cooking uncovered, stirring occasionally, until the gravy reduces to a thick, clingy consistency. This takes about 10-15 minutes. The oil should start glistening on the surface of the meat, indicating the 'peralan' stage is reached.

Final Seasoning
Sprinkle the Kerala garam masala and an extra half-teaspoon of crushed black pepper. Toss well for 2 minutes. The garam masala should be added last to preserve its volatile oils and fragrance.

Garnish and Rest
Finish with a fresh sprig of curry leaves and a teaspoon of raw coconut oil drizzled over the top. Cover the pan and let it rest for 10 minutes before serving, allowing the meat to absorb the final hit of spices.
Notes & variations
- Select young goat meat for the most tender ribs; older mutton will require more whistles.
- Coconut vinegar is traditional, but apple cider vinegar is a good substitute.
- For a drier 'Fry' version, continue cooking until the onions turn dark brown/black.
- Ensure the peppercorns are freshly crushed; pre-ground pepper loses its 'heat' and aroma.
Serve with
Serve with Kerala Porotta, Appam, or Ghee Rice.
Cook's note
Don't discard the fat on the ribs; it renders down into the masala, providing the authentic 'nadan' richness.
