I'm looking for ideas to make an insulated pot lid for baking. Flatcatgear offers a piece carbon felt that can be set on top of your metal pot lid, but I'm looking for something that can replace my metal pot lid completely.
I like the DIY lid in the thread below, but I am not ready to work with synthetics and epoxy quite yet. I'm hoping for a simpler solution such as styrofoam wrapped in tinfoil (if it won't melt).
Does anyone have recommendations for an easy DIY hard sided insulated pot lid?
