Buttery, soft burger buns or rolls.
Line a baking sheet with parchment paper. Divide the dough into 8 equal parts. Gently roll each into a ball, flatten slightly and shape into a disk. Arrange two to three inches apart on baking sheet. Cover loosely with a clean dish towel and allow to rise again for 1 to 1 1/2 hours or until the dough feels like a marshmallow when gently touched.
Preheat the oven to 400 degrees with rack in center. Beat remaining egg with one tablespoon water and brush the tops and around the sides of the bun. Sprinkle with sesame seeds, if desired. Bake baking, until tops are golden brown, about 15 minutes. Transfer to a rack to cool completely. Makes 8 4 to 5-inch burger bun.
