This is what I use, and it works for all my friends, I have on tap, the best greese and beef, and bacon run off drippings, pour over hard bread ends, add some sugar, add some popcorn, and bingo when this stuff heats up in a plastic pail, it's like a dinner bell!!!!
This will not work in a metal drum, you have to use 20lt white plastic pails. And the cost of a bag of sugar, sure beats the hell out driving all over to buy day old donuts
