Roast the Green Gram on a low flame until it gives out aroma. Let cool and wash it. (It takes about 15 minutes for the Gram to be roasted until fragrant)
Add Foxtail Millets, soaked overnight, Green Gram and Salt, pour 5 Cups of water and cook on medium flame until 4 whistles.
After 4 whistles, there would still be some Water in the Pongal. But it will disappear by the time the Pongal cools down.
Heat Ghee and add Cashew Nuts and the rest of the ingredients, fry until they give out good aroma and then add to the Pongal.
