They do great at home.
Not sure how they would do in a campfire ?
I would think maybe they wouldn't recommend it because of the vast differences in temperature that a campfire can be/get to, but I am just speculating here. I am also sure that it has/can be done as long as you pay close attention to your fire & your food. Others who are more edumicated on the subject will maybe chime in on this question ?
Edit: just used the 17" skillet to cook up 18 Italian sausages all at the same time. Came out awesome. We kept some out and vacuum sealed the rest .
