I'm starting a small bakery. Initially I'll be baking cookies. My question is: if I purchase a 5-rack full-size electric convection oven, how likely is it that I can load the oven with 5 full-size pans of cookie dough and get consistent even results without having to shift the pans around during the baking? I'm worried that the cookies on the top pan will bake out differently than the ones on the bottom pan, or the pans in the middle will be different, etc.
I'm considering a mini rotating rack convection oven for this reason, but I don't know if that's an unnecessary expense.
Also, if anyone can steer me to the best oven for the aforementioned purpose, I would appreciate it.
