Although the ingredients in curries may vary from one to the other, a good thumb rule is that a curry is a dish containing sauted onions, ginger, garlic and varying amounts of spices like turmeric, cumin, coriander, ginger, chili, cloves and fenugreek, among others.
A few days ago, I had an amazing curry made by grinding a coconut, fresh green chili, dried whole red chili and garlic sauted in coconut oil with raw mango and pumpkin, cooked to perfection and finished with coconut milk, jaggary and tamarind juice.
