Roast the spices. Roast the dried red chillies, coriander seeds, cumin seeds, peppercorns and fenugreek seeds until aromatic. Allow to cool.
Grind the masala. Grind the roasted spices with the grated coconut, turmeric, tamarind, garlic and salt, adding water as needed to make a smooth paste. Keep the onions aside for the next steps.
Brown the onions. Heat coconut oil in a pan and sauté a portion of the chopped onions until golden brown. Reserve some of the remaining onions for the gravy and, if desired, a little for the final tempering.
Cook the gravy. Add the ground masala and some raw chopped onion to the browned onions. Thin slightly with water and bring to a gentle simmer. Cook until the added onion is tender and the masala is cooked. Check the salt. As an alternative, grind this portion of raw onion with the masala instead of adding it separately.
Add the Pathrode. Gently add the steamed cubes to the gravy and heat through, taking care to keep the pieces intact.
Finish and serve. If desired, brown the reserved onion in a little coconut oil and spoon over the Pathrode Gassi. Serve hot.
