Inspired by Christine’s Recipes.
Extra rolls will freeze perfectly once baked — let cool and wrap well in a few layers of plastic wrap before freezing. To reheat, just microwave from frozen for about 30-40 seconds, or allow to thaw (still wrapped) to room temperature, then bake at 350 for a few minutes.
Instead of a flour paste cross, feel free to use your favorite pipable glaze, piped on after the buns are baked and have cooled.
