Milagai podi ( Gun powder)

Chana dal 2 cups        udad dal 2 cups       white sesame seeds, better still black sesame seeds as they've 400 & more calcium than the white one or what you can do use both equal quantity 1+1 cup or only white if you wish
red chilies to taste. As red chilies when you roast make you cough, best is use the quantity you need, half with each dal when you roast it with 2-3 drops of oil. roast each dal separately, roast sesame seeds/til also well. Cool & powder all together with salt to taste.

ps- Some people use less of chana dal, so you can use the dals as you like. But when you use til/sesame seeds, it not only enhances the flavour, but also gives you more calcium. Even if you use more til, it is ok, or even without til.

For non-south Indians, this is what we eat with idli, dosai, adai etc, as chutney is not made every day. This lasts long when stored properly. This is mixed with little of til oil & eaten with dosai/idli/ adai.
