Looking at this recipe, it seems to me there must be some mistake on either the pan size or the dough batch size. I could see if the recipe was supposed to yield two dough balls, or if the pan was supposed to be much larger, but by my calculations, this recipe produces over 1 kg of dough for a 1" x 12" x 16" pan, which sounds totally insane to me. That comes out to about 18.5 g of dough per square inch, as I figure it, which has to be at least three times the standard amount. I can't see how a pan that size could even hold that much dough without it going over the sides after rising.
