Sourdough Burger Buns

The perfect accompaniment to a good hamburger is a good bun: soft and flavorful, with enough body to stand up to condiments. These sourdough buns are fast and easy to make.
Ingredients:

1 cup fresh sourdough starter
1 1/2 Tbsp. olive oil
1/4 cup lukewarm milk or stock
1/2 tsp. kosher salt
1/2 cup whole wheat flour
1 cup white flour or bread flour
Sesame seeds (optional)

Instructions:

Stir together sourdough starter, olive oil, milk, and salt.
Add the flour, 1/2 cup at a time, mixing with a spoon until it comes together enough to turn out onto a bread board or clean counter top.
Knead the dough until it is smooth and satiny, about 10-20 minutes.
(Optional) Refrigerate the dough for up to 24 hours to get a more flavorful bun. Bring it back to room temperature before continuing.
Let the dough rest at room temperature 15-20 minutes, then roll it out 1/2 inch thick.
Use a 3- or 4-inch biscuit cutter to cut bun shapes and transfer them to an ungreased baking sheet. Re-roll the dough and cut more shapes until all the dough has been used.
(Optional) Press a light layer of sesame seeds gently into the buns.
Cover the buns lightly and let rise until doubled in bulk – between 1 and 4 hours.
Preheat the oven to 350°F. Bake buns 18-20 minutes.
Cool on the baking sheet for 5 minutes, then transfer to a wire rack to continue cooling. Cool completely before slicing in half horizontally.
