Fry the onion with cumin seeds, black peppercorns, chili, and curry leaves with ghee or coconut oil. If you use other greens like spinach, you can add it fresh.
When the veggies are soft and the spices are fragrant, add it to the food processor with yogurt and coconut. Whizz it all up till it becomes smooth paste. Add a little water if it’s thick, and season with salt.
For tempering. fry the mustard seeds with ghee or coconut oil but be warned they will pop and go all over the stove.So make sure you cover it when frying.
Serve it cold with rice or dip papadum, but you can dip anything in it.
