Did you ever put one of the shoe polish size cans of peanut butter inti a burning Yukon stove so that it would blow up and out the stove pipe, taking the soot out with it? Nothing like getting splattered with molten peanut butter.
Can't say I ever put anything "inside" of a Yuk Yuk ... lots of things on top; the few times we used Yuk Yuks. Winter Warfare School up in Alaska and then once or twice during winter warfare training deep up in the Italian alps.
We would use empty coffee cans to cook rabbit stew on top of the Yuk Yuks with melted snow and CRats salt.
