This is most likely nothing new, but I started making this several years ago for potlucks and food days at work The baking pan is a 15' cast irion skillet, and the rolls come out whole wheat, white and rye.
The recipe is not exact as to exactly what to use, but it starts with 6 cups of warm water, when your doughs are mixed up it it will be pretty right on with the amount needed to fill the pan. This gets 3 packages of yeast or the equivelant in bulk. I add a bit of sugar and a bit of salt if desired. Also I add a small lump or lard, maybe 1/3 cup. I then stir in enough white flour to make a batter about as thick as pancake batter. When the yeast has got it good and bubbly in about an hour, I stir it well mixing in the lard and then divide it between 3 bowls. In one I add enough white flour to make a white bread dough, the next I add enough whole wheat flour to make a whole wheat dough. The next one gets what ever is needed to make rye bread, this was pumpernickle because I didn't have the steel ground for my favoite Czech style and used some mollasses and some stone ground rye flour, plus of course caraway seed.
When the doughs have doubled I punch them down and make up rolls and place them in the well greased pan. When doubled in size again, bake at 375-400 till done, (35-40 minutes.) Brush with melted butter when done. This will drop right out of a well seasoned pan and when cooled can be wrapped.
