After a few months baking at home and selling here and there, we recently
found a shared-use commercial kitchen where we can rent a room on an hourly
basis. One problem: there's no proof box! They have floor-type Hobarts,
that oven that takes a whole cooling rack and spins it while it's baking, a
sheeter, depositors, etc. There is a lot of commercial equipment, but no
proof box. We are still small (a couple hundred $$ a week in sales), so we
can't afford to buy one (yet!). I would like to know if anyone has built a
proof box.

I have used cardboard boxes here at home, even tried the "dishwasher" method
(works OK), but I'm looking for a bigger, less-flimsy kind of thing. All I
can think of is using a Wardrobe mover's box and covering it with a tarp.
But I'd need a heat source and I guess I'd add a plastic panel so we could
see in without opening it.

Sooooo if anyone has any ideas about building a mobile (we can store it
there) proof box, I'd appreciate it. Right now we're baking cookies,
pastries and cakes there, so we don't need it yet, but we'd really love to
have a proof box.

Thanks All!
