Soft Bakery-Style Sourdough Hamburger & Brioche Buns
Sturdy yet cloud-soft sesame-topped sourdough burger buns that hold juicy burgers without crumbling or turning soggy
Soft Bakery-Style Sourdough Hamburger & Brioche Buns Baker's Formula & Schedule At A Glance
The Soft Bakery-Style Sourdough Hamburger & Brioche Buns is formulated at 67.0% apparent hydration (yielding 70.0% true total hydration once starter water and flour are factored in), featuring 90% Unbleached High-Protein Bread Flour / 10% Fine White Whole Wheat or Mashed Potato Flour, 20% active 100%-hydration levain, and 2.0% fine sea salt. Bulk fermented at 78°F (26°C) for 4 hours until 60% risen, followed by 2.0–2.5 hours at 78°F–80°F until puffy and 2.5x height, and baked at 390°F (200°C) with steam tray for 16–18 minutes until deep golden (200°F core).

Boundary Caveat: Static gram weights for Soft Bakery-Style Sourdough Hamburger & Brioche Buns assume 8 Bakery Burger Buns (124g each / 988g total) at 67% apparent hydration (70% true hydration with 20% levain); if your pan volume, loaf count, or starter hydration differs from 100%, use the interactive gram scaler below to rebalance main flour and water automatically.
Dough Rheology & Handling Dynamics
Physics of gluten hydration, elasticity, and tackinessIf burger buns are proofed as spheres without flattening, they bake into tall baseballs that tip over when loaded with toppings. Pressing relaxed 70.6% true hydration dough into wide discs redirects gas expansion upward across a 4.5-inch diameter footprint.

Step-by-Step Artisan Method
Carefully curated instructions designed for consistency, oven spring, and blistering.
Build Active Sourdough Levain
Phase: Levain BuildMix 1 part mature sourdough starter with 2 parts lukewarm water (78°F / 26°C) and 2 parts unbleached flour to yield at least 97g active levain (20% inoculation). Ferment for 4–5 hours until doubled, domed, and buoyant.
Enzymatic Autolyse & Hydration
Phase: AutolyseCombine the 487g total flour blend (90% Unbleached High-Protein Bread Flour / 10% Fine White Whole Wheat or Mashed Potato Flour) with 293g filtered water (90% of formula water) in a broad mixing bowl. Mix until zero dry flour remains, cover, and rest for 45 minutes.
Incorporate Levain, Salt & Enrichments
Phase: Mixing & BassinageDimple 97g active levain, 9.7g fine sea salt (2.0%), and the reserved 33g bassinage water into the autolysed dough. Work using the Rubaud method or stand mixer for 4–6 minutes until smooth, incorporating any recipe enrichments.
Bulk Fermentation & Strength Folds
Phase: Bulk FermentationFerment at 78°F (26°C) for 4 hours until 60% risen. Perform 3 to 4 sets of stretch-and-folds or gentle coil folds spaced 30–40 minutes apart during the first 2 hours, laminating any solid inclusions at the second fold.
Portioning, Pre-Shaping & Final Shaping
Phase: ShapingTurn the aerated dough onto the work surface to yield 8 Bakery Burger Buns (115g each) (8 × 115g). Pre-shape gently, allow a 20-minute bench rest for gluten relaxation, then execute final shaping with taut surface skin tension.
Final Proofing & Cold Retardation
Phase: Proofing & RetardProof according to schedule: 2.0–2.5 hours at 78°F–80°F until puffy and 2.5x height. Cold retardation at 38°F (3°C) slows yeast respiration while lactobacilli synthesize complex organic flavor compounds and organic acids.
Artisan Bake & Internal Cooling Cure
Phase: Bake & CureBake at 390°F (200°C) with steam tray for 16–18 minutes until deep golden (200°F core). Remove onto a wire cooling rack immediately after baking so bottom steam escapes cleanly, and allow starches to set before slicing.
Artisan Baker's Golden Rules for this Recipe
Account for True Total Hydration (70.0%): Because a 100%-hydration levain at 20% inoculation contributes equal parts water and flour, your true dough hydration is 3.0% higher than the 67.0% apparent water ratio.
Respect Desired Dough Temperature (DDT): Target 76°F–78°F (25°C–26°C) right after mixing so wild yeast and heterofermentative lactobacilli stay in optimal metabolic balance during 78°F (26°C) for 4 hours until 60% risen.
Master the Handling Protocol: Palm Flatten After Shaping Protocol: Shape into taut 115g balls, let rest 10 minutes on the parchment-lined sheet pan so gluten relaxes, then press firmly with a flat palm to flatten each ball into a 3.75-inch wide disc before final proofing.
Verify Thermal Doneness: Bake at 390°F (200°C) with steam tray for 16–18 minutes until deep golden (200°F core) and always confirm core starch gelatinization with an instant-read thermometer before cooling on a wire rack.
Frequently Asked Questions & Troubleshooting
Q:What is the difference between 67.0% apparent hydration and 70.0% true hydration in this Soft Bakery-Style Sourdough Hamburger & Brioche Buns?
Apparent hydration (67.0%) only divides formula water (326g) by main flour (487g). True total hydration (70.0%) includes the 48g water and 48g flour inside your 97g sourdough levain, reflecting the real physical moisture of the dough.
Q:How can I scale this Soft Bakery-Style Sourdough Hamburger & Brioche Buns formula for multiple loaves or different pan sizes?
Use the live Baker's Percentage Calculator above: adjust Target Loaf Count or Target Unit Weight (default 8 × 115g = 920g batch) and every flour, water, levain, and salt gram weight recalculates automatically while preserving 67.0% hydration.
Q:Why does my dough feel stickier than expected during bulk fermentation?
If burger buns are proofed as spheres without flattening, they bake into tall baseballs that tip over when loaded with toppings. Pressing relaxed 70.6% true hydration dough into wide discs redirects gas expansion upward across a 4.5-inch diameter footprint. Ensure your flour meets the recommended protein spec and keep your hands lightly damp or oiled rather than adding raw bench flour.
Q:Can I cold-retard this dough longer in the refrigerator for deeper sourdough tang?
Yes! Keeping your refrigerator calibrated between 36°F and 38°F (2°C–3°C) puts wild Saccharomyces yeast into dormancy while lactic acid bacteria continue producing organic acids for up to 16–24 hours.
