In a pan add the peanut and roast them on medium flame. Peel them and grind them coursely.

Now in a big bowl add soaked sabudana, peanut, mashed potatoes, green chilli, curry leaves, cumin seeds, lemon juice, salt, sugar and chopped coriander leaves. Start mixing, applying some pressure. Take spoonful of mixture in your hand and make round shapes and flatten it into a patty shape.

Heat the oil in a deep pan, drop the vadas in hot oil. Don't stir immediately, it might break or stick. Deep fry all the vadas on medium flame until it becomes golden brown and crispy.
