Prepare the Dough
In the bowl of a stand mixer, combine the sourdough starter, water, honey, and salt until well mixed. Add the bread flour and bring the dough together by hand into a rough, stiff ball. Attach the dough hook to the mixer and knead on low speed for 6-7 minutes, or knead by hand for about 10 minutes, until the dough is smooth and elastic. Cover the bowl with a clean towel or plastic wrap and let the dough rise at room temperature for 8-12 hours, or until it has visibly expanded and feels soft and airy.
Shape the Bagels
Line a baking sheet with parchment paper. Turn the risen dough onto a clean work surface and divide it into 8 equal pieces. Roll each piece into a smooth ball. To form the bagels, press your thumb through the center of each ball and gently stretch the dough to create a ring shape. Place the bagels on the prepared baking sheet, leaving space between them. Cover with a clean towel and let the shaped bagels rest for 30-60 minutes, or until they appear slightly puffy.
Prepare the Water Bath
Preheat your oven to 425°F (218°C), ensuring the oven rack is in the center position. In the meantime, bring a large pot of water to a boil and stir in honey until dissolved.
Boil the Bagels
Gently lower the bagels into the boiling honey water, working in batches of 3-4 at a time to avoid overcrowding. Boil each bagel for 2 minutes on one side, then flip and boil for another 2 minutes on the other side. Use a slotted spoon or mesh strainer to remove the bagels and return them to the parchment-lined baking sheet.
Add Toppings
While the bagels are still damp from the water bath, dip the tops into your preferred toppings, such as everything seasoning, sesame seeds, or coarse salt. Place them back on the baking sheet, ensuring the toppings face up.
Bake the Bagels
Transfer the baking sheet to the preheated oven and bake the bagels for 25-28 minutes, or until they are golden brown and crisp on the outside. Rotate the baking sheet halfway through the bake time if needed for even browning.
Cool and Enjoy
Once baked, remove the bagels from the oven and let them cool on a wire rack. Serve them fresh or store for later—they’re perfect for breakfast sandwiches, a toasted snack, or enjoyed plain with a smear of cream cheese.
