Since we are about ready to leave, believe it or not, on a trip to Nashville, I am thinking about cooking on the road. Mainly because I'm hungry and it's lunch time, I guess.
We had a memorable experience with attempted car cooking once. David knew the motor got hot when we rode, not overheated, just hot, so he put a dutch oven full of a dish we call goulash into the motor compartment of the car. All he wanted to do was heat the dish up, since he had cooked it the night before and kept it in the refrigerator overnight. We were going on a picnic at Natural Bridge, and he thought the goulash would be good to eat.
Guess what. Despite the fact that Natural Bridge is at least 60 (and maybe more--I don't have anyone here to ask about the distance) miles from our house, and despite the fact that the motor does get hot, the dish was not warmed up by the time we were ready for lunch. It was still pretty cold.
Nowadays I enjoy good food cold, (matter of fact, our motto is "If it was good to start with, it will still be good cold") but at that time, the whole thought was repulsive. I don't remember what we ate, but I do remember that the cooking experiment did not work.
