Sourdough Hamburger Buns

From redstaryeast.com

Makes: 18 Buns

Dough:
¾ cup warm water
1 cup fed sourdough starter
1 Tbsp vegetable oil
1½ tsp salt
1 Tbsp sugar
2-3 cups bread flour
2¼ tsp (one package) active dry yeast

1 egg, room temperature

Egg Wash:
1 egg
1 Tbsp water

Combine all of the ingredients except for the egg in mixing bowl for 4 minutes on medium speed. Add egg and beat 1 minute. Gradually add more flour and knead 5 to 7 minutes until smooth and elastic. Place dough in lightly oiled bowl and turn to grease top. Cover; let rise until dough doubles.

Turn dough onto lightly floured surface; punch down to remove air bubbles. Divide dough into 18 pieces. On lightly floured surface, shape each piece into a smooth ball. Place on greased cookie sheet. Flatten to a 4-inch diameter. Cover; let rise until indentation remains after touching. With scissors, make an “X” on the top of each roll. If desired, brush with egg wash (combine egg and water). Brush tops of rolls. Bake in preheated 400º F oven 15 to 20 minutes. Remove from cookie sheet; cool.
