Platinum Instant Sourdough Bagels

Platinum Instant Sourdough Bagels
A staple of the New York City culinary scene gets a sourdough makeover with Platinum Instant Sourdough Yeast. The bite from the sourdough and sweetness from the honey work together to create a perfectly balanced combination. See video tutorial below.
Yield 12 bagels



  • 5 1/2 cups (699g) bread flour
  • 1 (0.63oz) package (18g) Platinum Instant Sourdough Yeast
  • 4 teaspoons (12g) kosher salt (see note 1)
  • 1 2/3 cups plus 2 tablespoons (430g) warm water (120°F/49°C to 130°F/54°C)
  • 1 1/2 tablespoons (32g) barley malt syrup
  • 8 cups (1,920g) plus 1 tablespoon (15g) water, divided
  • 1/2 cup (170g) honey
  • 1 large (30g) egg white
  • Garnish: everything bagel seasoning


  • In the bowl of a stand mixer fitted with the paddle attachment, stir together flour, instant sourdough, and salt by hand. Add warm water and malt syrup, and beat at very low speed until a shaggy dough forms, about 1 minute. Switch to the dough hook attachment. Beat at low speed for 10 minutes. Increase mixer speed to medium-low, and beat until dough pulls away from sides and bottom of bowl, about 5 minutes. Check for proper gluten development using the windowpane test. (See note 2)
  • Lightly oil a large bowl. Shape dough into a smooth ball, and place in bowl, turning to grease top. Cover and let rise in a warm, draft-free place (75°F/24°C) until doubled in size, 30 to 45 minutes. (See note 3).
  • Place a large sheet of parchment paper on a counter in a warm, draft-free place (75°F/24°C), and generously dust with flour.
  • Divide dough into 12 equal portions (about 105g each). Shape each portion into a ball. Using your finger, poke a hole through center of each ball, stretching hole to 1 to 1½ inches wide. Place on prepared parchment. Cover and let rise until puffed, 15 to 30 minutes.
  • Preheat oven to 375°F (190°C). Line 2 sheet pans with parchment paper.
  • In a large stockpot, bring 8 cups (1,920g) water and honey to a low simmer. Carefully drop bagels, 1 to 2 at a time, into water, reopening holes slightly if necessary. Cook for 10 seconds per side. Remove from water, and place on prepared pans.
  • In a small bowl, whisk together egg white and remaining 1 tablespoon (15g) water. Brush dough with egg wash. Sprinkle with bagel seasoning, if desired.
  • Bake until golden brown, 20 to 25 minutes. Let cool on pans for 15 minutes. Serve warm or at room temperature.


  1. Salt weight and volume vary by brand. Diamond Crystal kosher salt was used in this recipe (1 tablespoon is 9 grams). If you a have different brand or type of salt, use the weight listed in the recipe, not the volume measurement. If you do not have a scale, check your brand’s website for what the equivalent volume measurement is for the weight listed in this recipe.
  2. To check for proper gluten development, use the windowpane test: Pinch off a small piece of dough, and carefully stretch to a thin sheet. If dough stretches into a translucent sheet without tearing, it is ready. If dough tears, it’s not quite ready.
  3. To test for doubling, quickly press the tips of two fingers ½ inch into dough. If dents remain, the dough has doubled in size.

Hi, I would like to know if i can put the bagels after shaped in the fridge to prof slowly, the reason I ask is because I have done bagels with starter that I made myself and I put them in the fridge after shaping them to prof for about 12 hours

Hi Marisa – Yes, that would work fine with this recipe.
Happy baking!

What is the purpose of 1/2 cup of honey? Other recipes call for only a couple of tablespoons of honey, molasses, or malt syrup, so I’m a bit confused about the amount needed.

Hi Linda,
Great question! The purpose of adding honey to the water bath is to add some sweetness flavor to the bagels. You can decrease the amount, just keep in mind that the less you use, the less flavor.
Happy baking!

I just discovered PISY and is it ever a game changer! I was wondering about using it to make bagels and am very happy to find a recipe for them! A couple of questions regarding the necessity for the barley malt syrup…what is it exactly needed for in this recipe and is there any other substitutions that could be used? Thanks!

Hi Gracie,
We’re thrilled that you are enjoying the Platinum Instant Sourdough prouduct! The barley malt syrup provides food for the yeast and also conditions the dough (helping to relax it for easier handling). You can substitute it with honey or molasses.
Happy baking!

Can I substitute malt flour for the barley malt syrup? If so how??

Hi Patricia,
We have not tested malt flour in this recipe, but you can certainly play around with it. Let us know how the bagels turn out!
Happy baking!
