This is one of my favorite Indian recipes. It's like nothing you have ever tasted before. You have to have a lot of curry leaves though and the dried powdered ones don't really work well in this recipe. It's a two step recipe. First you make the usili aka lentil cake. You can make it ahead and then the rest is easy. Or you can cook up the beans while the lentil cake is cooling. You HAVE to let the lentil cake cool, or it won't work. From Vegetarian Samayal of South India.
