I always use mild chilly powder in all my curries. So adjust the spices accordingly.
For this curry, I used maggi coconut milk powder. I mixed 3 tablespoon of powder with 1 and 1/2 cups of warm water. Sometimes I also use silk unsweetened coconut milk and the canned versions.
If you don't like coconut milk, add 1 cup of warm water.
If you are not using curry leaves, sprinkle some cilantro/coriander leaves in the end.
