I am looking to get into freezer bag cooking. I've been reading the FBC site and will use a couple of the recipes on on overnight in New Hampshire this month. If it is what I think it will be, I'll be buying the book the next day.
However, I don't want to spend a ton of money before I'm ready to commit, and that includes the $20 bucks for the foil lined bubble insulation that I've seen in one set of DIY instructions.
My question is, during the winter, will a makeshift fleece cozy (I've got dozens of fleeces hanging around) effectively insulate the bag, or is that insulation the only way to go?
Thanks in advance!
