You can also make it with leftover rice. :)
In a kadai heat one tablespoon of ghee/oil. First add peanuts or cashews, fry them until they turn light brown. Remove aside. Then add a little more oil & add cumin and mustard seeds, when they splutter add curry leaves first, split green chillies, chana dal, urad dal & potatoes (optional). Sauté them till golden and crisp. In the end, sprinkle half teaspoon turmeric for that golden yellow color. Mix and then sauté for another one to two minutes. Add the peanuts & cooked rice in the kadai with the sautéed ingredients, add salt (as per taste) & at last sprinkle a spoon or two of limejuice.
Note: Rice absorbs the limejuice & the tanginess you feel during the preparation reduces in intensity after sometime.
