1. Heat the 1 t oil in a wok or heavy skillet over medium heat for 3 minutes. Add the urad and channa dahl and chiles. Fry stirring constantly until the beans begin to turn color, about 3 minutes.
2. Stir in the asafetida and sesame seeds. Continue frying until the contents of the pan are nicely browned and smell roasted, about 3 minutes. Turn off the heat, transfer mixture to a plate and cool completely. Blend in the sugar and salt. Grind the mixture to a powder using a coffee grinder (my preferred method), or a large mortar and pestle or spice mill. The powder should be neither coarse, nor as fine as flour; it should have a grainy texture. This mixture stays fresh indefinitely if stored in an airtight container in a cool place. Optionally, just before serving, blend a little oil into as much powder as you might use to make a sauce.
addictive. I find myself eating it plain, unable to stop--but I'm a strange one. The recipe comes from Julie Sahni's Classic Indian Vegetarian and Grain Cooking. Some of the ingredients are specialized; you'll have to get them from an Indian foods store
