Blend the ingredients for the curry masala into a coarse paste with a little water. Soak a small lemon size tamarind in warm water and extract the juice.
Wash the goat head meat a couple of times in running water. Then add the meat into a pressure cooker with salt to taste and one cup of water. Pressure cook for at least 30 minutes.
Heat oil in a pot and add the masala paste. Also, add bottle masala and saute for 2 minutes. Add chopped tomato and saute till tomato softens.
Pick up all the loose bones from the pressure-cooked meat. Stain the stock too and pour the meat into the pot along with the stock. Add the tamarind extract and cover the pot and simmer for 4 to 5 minutes. Add 2 green chillies, slit.
Finally, garnish with coriander leaves and then switch off the heat.
Notes
Add any meat masala you like. Adjust masala to suit your taste
Slit green chillies are optional, you can skip them.
Use lemon juice instead of tamarind.
Strain the stock and pick up the soft bones from the meat. Straining the stock will get rid of all the fine bones settled in it.
