Sourdough hamburger buns are a delightful twist on the classic bun, combining the tangy and complex flavors of sourdough with the softness and lightness of a traditional burger bun.
Cover the bowl with plastic wrap and place the bowl in a warm spot. Let it rise for 6-8 hours until the dough is at least double in size.
Once the dough has doubled in size, place ¼ cup of flour on your work surface and turn out the dough. Cut the dough with a bench scraper into 8 equal pieces for larger buns, 10 pieces for smaller buns.
Shape the buns into a tight ball. Place them on a parchment paper lined baking sheet. Let the dough rest for 1 hour.
Preheat the oven to 400 degrees. In a small bowl mix together one egg and one tablespoon of water. Brush the tops of the shaped buns with the egg wash mixture. Sprinkle with sesame seeds. Bake the buns for 25-30 minutes or until golden brown.
