Instructions
Mix the dough
In a medium bowl, stir together the sourdough starter, egg yolk, and salt until smooth. Add the flour and baking powder (if using), mixing until a stiff dough forms. It should be firm but still workable.
Knead and rest
Turn the dough out onto a floured surface and knead gently for 1–2 minutes, just until smooth. Cover with a towel and let it rest for about 10 minutes—this step helps the dough roll more easily.
Roll and cut
Roll the dough thin, about ⅛ inch thick. Cut into strips roughly 1 inch wide and 2–3 inches long. They’ll puff a bit as they cook, so thinner is better.
Cook in broth
Bring your chicken broth to a gentle simmer. Drop the dumplings in one at a time, stirring occasionally so they don’t stick together. Simmer for 12–15 minutes, or until tender with a slight chew in the center.
