The most delicious, soft, and buttery sourdough hot dog buns you'll ever have! These sourdough discard hot dog buns take about 3 hours to make from start to bake. They're perfect for any summer BBQ.
In a bowl, stir together the warm milk and sugar until dissolved. Add sourdough starter and yeast and stir to combine.
Add flour and knead until a dough forms.
Knead in the softened butter in small portions, then the salt.
Knead the dough until completely smooth, should take about 5 minutes.
Transfer dough to a bowl lightly coated with olive oil or butter.
Cover with a damp towel. Let rise at a warm temperature until nearly doubled, (about 1-2 hours, depends on the temperature).
Line a sheet pan with parchment paper.
Divide dough into 8 equal balls (each portion is about 108 grams) and place on the parchment paper lined pan.
Let the divided portions rest for 30 minutes.
Rolling in-between your hands, shape each portion of dough into a log, about 7-inches long.
Arrange dough on a parchment paper baking sheet, slightly apart so that the buns will touch when the dough doubles in size.
Let rise at a warm temperature until doubled, about 45 minutes. (I place the pan on top of the oven while it preheats for a warm proof)
Preheat oven to 375° F.
Combine egg whites with a teaspoon of water to create an egg wash and brush the top of the buns.
Bake for about 25 minutes or until golden, rotating halfway through if needed.
Remove from oven and immediately brush with melted butter. Let cool a bit then pull the buns apart.
Slice the buns along the top to serve. (see picture above recipe)
