First wash and cut the tilapia into 1 ½-inch pieces. If you are using whole fish then you need to remove the scales, head, fins, and internal organs.
In a bowl add ½ cup warm water and soak the 2 Garcinia cambogia / brindleberry, Malabar tamarind/ kudam puli for at least 30 minutes.
In an earthen pot or sauce pot add 1 tablespoon coconut oil and ¼ teaspoon mustard seeds when it starts popping add chopped onion, salt, and ginger. Adding salt will speed up the cooking of onion.
Then add a green chili and 1 sprig curry leaves. Cook until the onion becomes translucent.
To this add Kashmiri chili powder /sweet paprika, red chili powder, coriander powder, fenugreek powder, turmeric powder. And fry until raw smell goes about 2 minutes
To this add soaked Malabar tamarind/ Kudam puli along with ½ cup water. Then to this add 2 cups water and bring to boil .
Then add fish pieces and tomato and cover with lid and continue to cook.
After 10-12 minutes remove the lid and add rest of coconut oil and curry leaves.
