Tip 1: Use Your Face as a Trivet
When in a pinch, just place your face against the windowpane to keep it warm while you cook. It's like a free trivet, and you're already wearing it!
Tip 2: Cook in a Suitcase
Just place your food in a suitcase, close the lid, and leave it on the roof. It's like a thermos, but without the thermos.
