Check Your Starter: Ensure the sourdough starter is ready by confirming it has doubled in size and shows plenty of bubbles on the surface and sides of the jar.
Mix the Dough
In the bowl of a stand mixer (or using a Danish dough hook), combine the sourdough starter, water, honey, and salt.
Add the flour, attach the dough hook, and mix on the lowest speed until a rough dough forms.
Continue kneading with the mixer on low speed for 8-10 minutes, or until the dough is smooth and elastic.
Cover the bowl with a damp towel or plastic wrap and let the dough rest at room temperature for 8-12 hours. You can also rise overnight and continue with the following steps the next morning,
Shape Bagels
Line a baking sheet with parchment paper.
Turn the dough onto a clean work surface and divide it into 8 equal pieces (or 6 pieces if you want a larger bagel).
Shape each piece into a smooth ball, then use your thumb to poke a hole through the center of each ball. Gently stretch and shape the dough into a bagel ring, then place it on the prepared baking sheet.
Cover the shaped bagels with a towel and let them rise for 2-4 hours, or until puffy.
Water Bath and Bake
Preheat your oven to 425°F (220°C).
Bring a large pot of water to a boil and add 1 tablespoon of sugar.
Boil the bagels in batches of 3-4, cooking each for 2 minutes per side.
Remove the bagels from the water using a slotted spoon or mesh strainer and place them back on the parchment-lined baking sheet. Sprinkle with your desired toppings.
Bake the bagels for 25-28 minutes, or until golden brown.
