Cast Iron Skillet on the coleman stove.
We let the grease cool and put it in coffee containers and then to the dumpter once we are done with it.
We have a larger deep fryer with basket for when we are doing large groups that we bring from home. It stores grease in the unit like the fry daddy but we usually let it cool and put it back into a plastic jug with a lid for safe traveling and less chance of spillage during travel. We only bring it if we are going to have a large fish fry or be doing a bunch of french fries or fried chicken.
