I have a batch of hot dog and hamburger buns finishing their second rise right now. Based on the mold size, I rolled my dough to 1/2" thick and cut out a piece of dough 6" x 2", then weighed the dough. It comes to 4-3/4 oz per bun. The buns I make use 2-1/2 oz of dough, and this gives a finished roll that is adequate for a standard hot dog. I could not find anything on that website that suggested a certain weight of dough per bun, but I would imagine it should be about half of the cavity size to allow for rise and oven spring. The 4-3/4 oz is, IMHO, way too much dough for the mold, and would overwhelm a typical hot dog or brat. I will be posting a picture sequence of this batch of buns once they are out of the oven and cooled a bit, and give a finished size. I rolled them to 6" in length before setting them to the side for proofing.
