i need to pour chocolate in a tube. (about 2" PCV pipe) Was thinking about lining the tube w/ parchment or wax paper rather than messing with the band saw & trying to cut it lenghtwise, then clamping it back to make the mould. Lining seems like a more likely way to keep my fingers. Line the tube, put on the end cap, pour in the chocolate, let it set, then slide the whole thing out & peel off the paper for a beautiful, round, solid, chocolate thing. (that's the plan...) What to line with will peel off afterwards? & should I spray w/ anything?
