I made a cozy today. It came in heavy at 4 oz but, I think that I will be able to actually bake in it if I wanted to take Bisquick with me.
I took an insulated nylon lunch box and cut it down to fit my grease pot. I then coated the interior with aluminum tape and bound it back together with duct tape on the outside.
Looks really ugly but it really works. I placed a rice dish into simmer after just getting it boiling and 20 min later it was too hot to eat for another 15 minutes.
The plus is that my stove, measuring cup, grease pot, wind screen, scrubbing pad, spoon and pot stand all fit inside.
