If you want to make larger loaves instead of buns that's totally fine. You don't need to change a thing in the recipe. When I make this bread for the farmer's market I use disposable bread pans. I divide the dough into four equal parts. You can then simply work each part into a loaf, place it in the oiled pan, brush with egg and sprinkle with sesame seeds, let it rise, and bake. Or you can divide each part into three parts, braid the three parts and make a braided loaf. Add it to an oiled pan, brush with egg and sprinkle with sesame seeds, let it rise, and bake.
