How did you upgrade your proofing box?
Assuming that you've experimented over the years, what do you consider the minimum practical size for a proofing box, and how do you provide controlled, even heat? Does your box use radiant heat or convection heat?
My proofing box is a styrofoam container for shipping medicine (thick-walled but small). I use a pet heating pad, and ambient temperature depends on how much of a crack I leave with the styrofoam lid! Since the pad is small, I need to rotate the bowl of dough periodically.
Time to upgrade. I don't want to use the heating pad this time because its temperature is not adjustable (and the cats have dibs on it in the winter).
