If you ever find yourself with no cooking fuel for your stove top and you can't cook outside over a fire pit, get several votive candles and place them under the burner rack encircled around the burner. Light them all and put your pan on the burner as usual. This will produce enough heat to re-heat fully cooked, small items. I tried fully cooked burger patties and hot dogs in a cast iron pan. It takes a bit longer, but it will give you hot food.
