Remove curry leaves from the stems before using and discard the stems.
Slice the leaves into thin ribbons and add them to curries, dals, chutneys or salads.
Heat a teaspoon to a tablespoon of oil over medium-high heat. Add curry leaves to the oil and cook them for one to two minutes, then add prepared vegetables, rice, dal or meat and cook for a few more minutes, depending on the dish.
Heat curry leaves and other spices used in Indian cooking, such as mustard seeds or cumin seeds, in oil until they begin to sizzle. Strain the oil, then brush it on bread or stir it into plain yogurt for flavor.
Place the leaves in a basket, and put the basket in a cool, dark area of the house for three to five days to dry them. Use whole or crumbled dried leaves in the same way as fresh leaves.
