How to Make It
Wash the rice in several changes of water. Drain thoroughly. Combine rice, salt and water in a medium pot and bring to a boil. Cover tightly. Reduce the heat to very low and cook for 25 minutes.
Add the oil in a large frying pan, heat the oil over moderately high heat. When hot, add the mustard seeds. As soon as they begin to pop (a matter of seconds) add the curry leaves. Stir once and pour the contents of the frying pan over the rice. Add the lemon juice and zest and mix gently with a fork. Mix again as you transfer the rice to a serving dish.
