It's off topic, but not entirely.

Some years ago, I worked on tugs that had cast iron stoves, fired by diesle fuel. If you lit the stove, the whole galley got warm. If you did it in summer, the temperature in the galley would be unbearable.

I wanted dinner, was willing to cook, and we only had some much on board. My ingredients would allow me to make baked ziti, but I did not want to crank up the stove. We had a little Weber grill and used it to bake the ziti. I filled it up with coals, as soon as some of he coals were pretty hot, the ziti went on, the lid went on top and an hour later we ate. It worked. Wasn't he best meal I ever cooked, but it was good enough.
