Sourdough bagels are a great way to make homemade bagels at home! These bagels have a crisp crust, a chewey interior, and are a flavorful and perfect way to use your sourdough starter!
1. In the bowl of a stand mixer, combine the starter, milk, flour, and brown sugar with the batter beater on low speed. You just need it to be combined.
2. Switch to the dough hook and mix on medium-low speed until the dough is smooth, strong, and rubbery. It is a stiff, strong dough. This should take 2 or 3 minutes.
3. Dump the dough on the counter (you don't need to add any flour to the counter) and knead by hand for a few turns, or until the dough turns into a satiny, tight ball. Check the gluten development by stretching a small piece of the dough between two fingers. It should stretch really thin without breaking (this is called the windowpane test).
