Mix well into dal. Put mixture in a heavy saucepan and cook till a soft lump is formed Take care to stir continuously, so as not to charr. Keep aside. Mix ghee, flour, add enough water to make a soft pliable dough. Take a morsel sized ball of dough, roll into a 4" round. Place same sized ball of filling in centre, life all round and seal. Reroll carefully to a 6" diameter round. Roast on warm griddle till golden brown. Repeat other side. Take on serving plate. Apply a tsp. of ghee all over top.

Shallow fry on griddle like a paratha for a better flavour. But this method will consume more ghee and therefore calories. Serve hot with dal or amti.
