Pressure cook goat chops: Wash and clean goat chops and add to a large pressure cooker with enough water to immerse the meat. Add ginger/garlic paste, chili powder, coriander powder, turmeric powder, chopped shallots/ onion, chopped green chilies, salt and mix well. Pressure cook for 3 whistles and let it sit for some time until the pressure releases on its own.
Achari seasoning: Take a wide nonstick pan, pour sesame oil, when hot, add the tadka ingredients in one go, fry for few seconds until slightly browned (do not let the mustard splutter), add curry leaves and fry for few seconds.
Adding some tomato to this recipe is optional, but if you chose to add, do not add too much, fry them well. Then add chunks of green mango slices (star of this achari recipe) and fry for few mins.
Add the pressure cooked mutton chops along with the stock, coconut paste, mix well, check salt and let it simmer stirring occasionally until it dries out (or remove early if you want it in curry stage).
Drizzle some lime juice (if preferred) and garnish with chopped coriander leaves and serve.
