Remember buddy burners from scout camping? - adults can
make good use of them too… Thoroughly clean some empty
tuna cans. Cut corrugated cardboard strips as wide as a tuna
can is deep. Roll the strips up tightly until they’re the
size to just fit into the cans. Pour melted paraffin into
center of the tuna cans until they’re almost filled. When
you light the cardboard with a match, the Sterno-like fuel
will burn for quite a while for cooking over.
