Question: I'd like the rise the bread on a baking pan inside this thing. What is a good size to go with?
Document: I didn't know such a thing existed before I read a mention of it on a baking forum. I had been proofing my bread in the oven as I keep the house quite cool (low 60's in the winter). I'd set the oven to "warm" and then let it cool to about 85 deg, put in the greased bowl with the dough ball and then wait. I'd repeat the process for the second rise in the bread pan.
The only limitation I have experienced is having the right size pan for the proofer. The pan I use for cinnamon rolls and such does not fit. This is a 9 x 13 inch pan but with handles---the standard Pyrex baking dish in other words. If you like making yeast breads, I think you would find the proofer to be a handy tool.
I purchased this about a month ago. I'm  long time bread baker and I'm good at it. But even bread won't forgive uneven rising temps, no humidity,etc. It will rise, but not as perfectly as you'd like.No more rigging the microwave with  cups of hot water and all the other things I've used.This baby works . No need to cover the bread, water in the proofer pan gives the right amount of humidity. Every loaf rises consistently.
Update after a few loaves:I've run a few loaves of white bread and a few baguettes through the proofer. The results are consistent. I get a nice rise with no drying out of the dough. The temperature seems to come up quickly enough and remains constant. Staying within the size limits of the proofer I'd say this product is outstanding.On the Saturday evening I received the proofer I forwarded my review to Brod & Taylor.
This thing does exactly what its advertised as doing - the only two flaws I could talk about would be how the box walls don't fit very snuggly so a lot of heat escapes and that when its all folded in for storage the power cable is a little difficult to position so the lid latches shut. Otherwise this is a good product and I'd recommend it to others.
I have always wanted a proofer for my part time baking needs. Most of them are metal boxes that take up room not to mention the expense.Berkshire had just what I needed for size while in use and then it folds up and can go in a drawer, what a great idea. I think is it just perfect for the partime baker. It is plastic and cleans up very easy with a damp cloth.
This proofer is very easy to set up , clean, and fold. Temparature is shown both in Ferreinheit and celsius, which was crucial for me who use Japanese recipes for baking. However, the size of the proofer is too small to fit a half sheet pan. This is crucial since you really don't want to move a shaped and proofed dough. It is neccesary to proof and bake them in the same pan. I highly recommend the company to come up with a product that would fit a half sheet pan.
The skin of the dough did not seem dry. The final product is as good as any white sandwich bread I've made.There is not much I don't like about this unit. The power cord is very short which I think is odd for a larger kitchen appliance. It is not the size of a toaster which can fit nicely under a counter close to a power outlet. This unit has to be out in the open so at least for me an extension cord is a necessity - which I do not like.
My house temp varies from 62 at night to 70 during the day in the winter. Not very good for a long slow controlled rise for sourdough ( 16 hours) The proofer solves that and my sourdough is now amazing. Baking good bread has become an obsession the last few years and this proofer is the final tool in my arsenal.
I've only messed up one loaf by allowing it to rise too high on the second rise.So for under $150 I see this proofer. Based on the price and the way it seems to fold for storage along with the maintainable proofing environment it seemed too good to be true. I was also wondering why some of the big names in kitchen appliances don't make such a thing.
Answer: Regarding the loaf pan I mentioned, I can get two of the loaf pans in, but when I put in two of the Cusinart with the handles they are hard to get out when the bread has risen.
