Okay, let me see if I'm following you here. You boil the fat that's been removed from, say, a soup (stock?). You cool it and...remove from water and heat it to drive off the liquid? You lost me there! Starkman ← When you take the fat slab off of a cooled stock there will gunk stuck to the bottom of it. So reheat it in clear water then chill the pot till the fat is a slab again Then heat up the slab to remove any trapped water Then freeze or use tracey
