Start by adding the lamb trotters to a pressure cooker or your Instant Pot along with the whole spices- the bay leaf, cinnamon, black peppercorns, cumin, salt, turmeric, 1 teaspoon ginger-garlic-chili paste and let it cook on low heat for an hour.
Heat 4 tablespoon oil in a large pot, add in the thinly sliced onions and allow it to cook until the onions turn translucent.
Next, add in the tomatoes and give it all a good mix. Then add the chili powder, coriander-cumin powder and the remaining 1 teaspoon ginger-garlic-chili paste and allow it to cook again for a few minutes until the mixture gets fragrant.
Allow this to cool down completely and then blend this into a smooth paste.
Heat the remaining 2 tablespoon oil in the same pot and add in this paste along with the cooked lamb trotters and let this simmer for 10-15 minutes.
Add in the green chilies, garam masala powder, lemon juice and julienned ginger and give it all a good mix.
Top with a generous sprinkle of chopped coriander leaves and serve hot!
Notes
You can make the Paya curry even without the pressure cooker. Just remember that the lamb trotters need to be cooked to perfection, and that using a regular pot may translate into longer cooking time.
Want the curry to have a thicker texture? You can prepare a simple slurry using a bit of chickpea flour and water and add it into the curry while it is still on heat, slowly, while whisking it constantly.
To speed up the cooking process, you can also cook the lamb trotters with a bit of meat tenderizer added in. This will also help the goat trotters absorb the flavors better.
To lend this curry a nice smoky flavor, you can choose to grill the whole onions over an open flame, grind them into a paste and then use them for the recipe.
You can also use ghee instead of oil for this recipe to make the curry taste even better!
Use some whole wheat flour to rub the lamb trotters and 'clean' it. You can then wash them off or use them as is, in the recipe.
I used a pressure cooker to make this goat paya curry, but you can also choose to use your Instant Pot if you want to.
