If you would like to split up your time you can chill your sliced rolls before baking.
After step 11, cover with saran wrap and put in the refrigerator, and chill over night or for up to 16 hours.
When you are ready to bake the rolls, place a boiling pot of water on the bottom shelf of a cold oven and the rolls on the top shelf. Don't forget to remove the saran wrap. Leave in the closed oven to proof for 30 min.
After 30 min, remove the pot of water and rolls from the oven, and preheat to 350°F and bake as directed above.
