Ingredients
180 grams milk, lukewarm
50 grams granulated sugar
185 grams ripe sourdough starter
58 grams (1/2 stick) unsalted butter, very soft
1 large egg, lightly beaten
245 grams cooked sweet potatoes, mashed and cooled (1 10-ounce package frozen sweet potatoes steamed according to package instructions OR 2-3 sweet potatoes roasted at 375°F for 1 hour, then remove skins, mash while warm, and let cool)
1 teaspoon instant yeast (optional but recommended)
500 grams all purpose flour
11 grams (1 tbsp) sea salt
Semolina flour, for dusting baking sheets
Egg wash: 1 large egg beaten with a splash of milk
Sesame seeds for topping, optional
Instructions
In the bowl of a stand mixer, combine all ingredients. Using the dough hook, mix on low speed until dough comes together, then increase speed to medium/low for 7-10 minutes until sides of bowl are coming mostly clean. This dough will be rather sticky.
Transfer to large bowl sprayed with nonstick spray. Cover and let proof at room temp about 1 ½-2 hours until doubled.
Prepare 2 baking sheets by lining with parchment and dusting with semolina.
Using floured hands, shape into 10 balls, about 124 grams each. Be sure to form the balls into a nice, tight shape and build surface tension so they rise up nice and round. Arrange on prepared baking sheets (5 buns each), leaving several inches between the buns.
Cover and let proof at room temperature about 1 hour until nice and puffy. Meanwhile, preheat oven to 375°F.
Brush buns with egg wash and sprinkle with sesame seeds if desired.
Bake at 375°F for 18-23 minutes until deep golden. Internal temp should be around 190-200°F.
Transfer to wire rack to cool before slicing.
Notes
Enjoy with your favorite burger patty, pulled pork, breakfast fixins, grilled chicken, or any sandwich goodies you can think of. For best results, cut in half, spread with butter, and toast the inside of the bun on a skillet or griddle until golden.
