In a bowl of a stand mixer, or a large bowl, combine the sourdough starter, warm water, and honey or sugar, at low speed. Stir until the mixture is well combined.
Add the flour, and salt. Mix until a dough forms. If the dough feels too sticky, add a little more flour, one tablespoon at a time.
Knead the dough for about 8-10 minutes on a floured surface until it becomes smooth and elastic. Alternatively, use a stand mixer with a dough hook for 5-7 minutes.
