These authentic, New York-style sourdough bagels feature a beautifully shiny, blistered crust with a dense, signature chewy interior crumb. By utilizing a low-hydration stiff dough matrix and a traditional boiling step before baking, the starch surface gelatinizes perfectly, creating an iconic, unbeatably glossy finish.
Servings 8 Large Bagels

Ingredients

Sourdough Starter Levain (Night Before)
  • 10 g Sourdough starter culture
  • 50 g Water
  • 50 g Bread flour
The Stiff Bagel Dough
  • 450 g High-protein bread flour (100%)
  • 240 g Water (53.3%)
  • 100 g Active sourdough starter levain (22.2% - From the stage above)
  • 10 g Honey or barley malt syrup (2.2%)
  • 10 g Fine sea salt (2.2%)
The Boiling Bath & Toppings
  • tbsp Honey or barley malt syrup (For the boiling water)
  • tsp Baking soda (For the boiling water)
  • Everything bagel seasoning, sesame seeds, or poppy seeds (Optional)

Equipment

  • Large Pot (For the boiling water bath)
  • Slotted Spoon or Spider Strainer (To flip and cleanly retrieve the boiling bagels)
  • Stand Mixer (Highly recommended, as kneading a stiff 53% hydration dough by hand requires immense effort)

Method

Night Before – Levain Optimization
  1. 10:00 PM – Starter Build: In a small glass jar, combine the 10g of starter culture with 50g of water and whisk together cleanly. Stir in 50g of high-protein bread flour. Mix thoroughly, cover loosely, and let it sit at room temperature 72–76°F (22–24°C) overnight for 8 to 10 hours until the starter reaches its peak and at least triples in volume.
Day 2 – The Stiff Dough Mix & Bulk Rise
  1. 8:00 AM – Mixing the Base: In your stand mixer bowl, combine all 240g of water, 100g of your active overnight starter peak, 10g of honey, and 450g of bread flour. Mix with a heavy spoon just until a rough, dry, shaggy mass forms. Cover and let it rest for 20 minutes to jumpstart protein hydration.
  2. The Heavy Structural Knead: Add the 10g of fine sea salt to the bowl. Attach your dough hook and mix on low speed for 3 to 4 minutes until the salt integrates. Increase the speed to medium-low and knead continuously for 7 to 8 minutes. (The Stiff Dough Rule: This dough is exceptionally stiff at 53% hydration; the mixer will labor, but continue until the dough forms a completely smooth, dense, and uniform ball that clears the sides cleanly).
  3. Primary Bulk Proof: Shape the tight dough into a ball and place it into a clean bowl. Cover tightly and let it ferment at a warm room temperature of 76–80°F (24–27°C) for roughly 4 hours. Because of the low moisture levels, the dough will not double dramatically but should look visibly puffy, relaxed, and lighter to the touch.
Day 2 (Afternoon) – Portioning, Shaping, and Cold Retard
  1. 12:30 PM – Dividing the Portions: Tip the firm dough out onto a clean, completely un-floured work surface. Using a bench scraper and a kitchen scale, divide the dough mass cleanly into 8 equal portions (weighing roughly 110–115g each).
  2. Tension Ball Preshaping: Take a portion of dough, cup your hand over it, and roll it firmly against the counter in a tight circular motion to form a perfectly smooth, taut ball. Repeat for all 8 portions. Cover them with a damp towel and let them rest on your counter for 15 minutes to relax the tight gluten.
  3. The Finger-Poke Ring Shape: Dust your counter lightly with flour. Take a rested dough ball, flatten it slightly, and push your thumb straight through the exact center to create a clean hole. Insert both index fingers into the opening and spin the dough in mid-air or against the counter to stretch the hole outward until it expands to about 2 inches in diameter. Repeat for all 8 rings.
  4. Cold Fermentation Retard: Place the shaped bagel rings onto a baking tray lined with parchment paper that has been lightly dusted with cornmeal or flour. Cover the entire tray tightly with plastic wrap to prevent a dry skin from forming, and slide it directly into your refrigerator for a long, cold retard lasting 14 to 24 hours.
Day 3 – The Alkaline Boil & High-Heat Bake
  1. Next Morning – Boiling Station Setup: Preheat your home oven to 425°F (218°C). Bring a large, wide pot of water to a rolling boil. Stir in 1 tablespoon of honey (or barley malt syrup) and 1 teaspoon of baking soda. Set up a wire cooling rack next to the pot.
  2. The Active Gelatinization Boil: Remove the cold bagel tray from the refrigerator. Drop 2 or 3 bagels carefully into the boiling water bath at a time. Boil for exactly 1 minute, then flip them over using a slotted spoon and boil for 1 additional minute on the reverse side. (The Puff Factor: The hot water expands the internal gasses while gelatinizing the exterior surface starch).
  3. Dressing and Baking: Retrieve the bagels with your slotted spoon, letting excess water drain for 5 seconds, and place them back onto the parchment-lined baking sheet. If applying toppings like everything seasoning, sprinkle them on immediately while the bagel skin is still wet and sticky.
  4. The Blister Bake: Slide the tray immediately onto the middle rack of your preheated oven. Bake at 425°F (218°C) for 20 to 25 minutes until the crust turns an incredibly deep golden-brown with tiny surface blisters. Transfer to a wire rack to cool down for at least 20 minutes before slicing!

Notes

  • The Thermodynamic Secret to the Perfect Chewy Texture: Bagels owe their signature dense, chewy bite to a strict combination of low dough hydration (53%) and the boiling water step. Boiling the raw, cold dough right before it enters the oven instantly cooks and gelatinizes the exterior wheat starches. This forms a structural shield that traps expanding gasses inside, forcing the interior crumb to remain dense and tightly packed rather than expanding into airy, light bread.
  • Why Baking Soda and Honey belong in the Boiling Water: Adding baking soda to the boiling water increases its alkalinity, which dramatically speeds up the Maillard browning reaction in the oven, giving your bagels their iconic deep, glossy mahogany color. Meanwhile, the honey or barley malt syrup adds a subtle sweetness and creates a sticky exterior coat that securely anchors your seeds or seasonings to the crust.
  • Preventing the Dreaded Hole Close-Up: When executing step 7, stretch the center hole of your dough rings until it seems excessively wide (about 2 inches across). Sourdough dough has powerful elastic memory; as the bagels proof in the fridge and hit the boiling water, the surrounding dough will swell inward significantly. Stretching the holes widely ensures they don't seal up entirely during the oven spring.
