If making blueberry bagels, place the freeze-dried blueberries in a small bowl.Lightly spray them with water 5–6 times using a spray bottle, or add a couple tablespoons of water and toss to coat.This helps rehydrate the berries slightly so they don’t pull moisture out of the dough.Set aside.
Mix the Dough
In a large bowl, combine:active sourdough starterwatersugarfloursaltMix until a shaggy dough forms. Some dry bits of flour are fine.Cover the bowl and let the dough rest for 30 minutes.
Stretch and Fold
After the rest, perform the first stretch and fold.If making blueberry bagels, gently fold the blueberries into the dough during this step. They may fall out as you fold — just press them back in as best as you can.Cover the dough and rest again.Repeat the stretch and fold process two more times, allowing the dough to rest between each set.
Bulk Fermentation
Let the dough continue fermenting until it is:nearly doubled in sizedomed on topsoft and airyThis usually takes about 5 hours total from mixing, depending on your kitchen temperature.If your house is cooler, fermentation may take 5½ to 6 hours.
Cold Rest Overnight
Once bulk fermentation is complete, place the entire container of dough in the refrigerator overnight.This helps develop flavor and makes the dough easier to shape the next day.
Shape the Dough
The next day, turn the dough out onto your work surface.Stretch it into a rectangle roughly 16 inches long and about 5 inches tall.Roll the long edge of the rectangle into itself to create a long cylinder of dough.Cut the cylinder:first into two 8-inch sectionsthen cut each section into four piecesYou should end up with 8 pieces of dough.Each piece will look like a small round puck.
Form the Bagels
Let the dough rest for a minute if it feels tight.Then poke your finger through the center of each piece and gently stretch the dough into a ring.Stretch the hole slightly larger than you want the final bagel to be — the dough will naturally shrink back a little.Place shaped bagels on a parchment-lined baking sheet.Cover with a damp kitchen towel.
Final Rise
Let the bagels rise until:puffylightnoticeably larger than when shapedThis usually takes:4–5 hours at room temperatureorabout 3 hours in a warm spot (such as in an oven with the light on).
Boiling the Bagels
Preheat oven to 425℉.Near the end of the rise, fill a large pot ¾ full with water and add:1 heaping tablespoon honeyBring the water to a rolling boil.Gently lift each bagel and drop it into the boiling water.Boil:30 seconds on the first sideflip30 seconds on the second sideRemove with a slotted spoon and place on a parchment-lined baking sheet.
Baking
Bake at 425°F (218°C) for 15 minutes.Rotate the pan if needed to prevent uneven browning.Bake for an additional 7–8 minutes until golden brown.
Cool and Enjoy
Allow the bagels to cool slightly before slicing.The inside will be soft and chewy with a lightly crisp crust.
Notes
This recipe can be used for plain or other flavored bagels. Just swap out the blueberries for your ingredients of choice. If you want to make everything seasoned bagels, sprinkle the seasoning mix on right after taking them out of the boil. This helps it stick very well.
