Here is a proof box I built. It works pretty good, the only thing I may move the light (heat) on the top in the middle as now the bread is warmer in the back as in the front. The light is hooked up to a reostat so I can contol the temp. Also it has a 60 watt bulb. Winter will be the real test. And I may add some water for dampness. Sourdough starter on top shelf.
That should work very well. shows you hae givin quite a bit ot thought to this. Water all ways helps.. I used to get my dish washer good and warm and then slip my loaves in to proof. which worked just like the real thing. Keep on baking. Nothing like a good fresh loaf of home made bread.
I share the dishwasher idea. I use it and I love it. I run a quick rinse and stop it in mid cycle, before it drains. I have a nylon bread board that just fits in the bottom shelf.
I too would like the recipie if you are willing to share.
