Soft Sourdough Sandwich Bread (Pullman Loaf)
Pillow-soft, fine-crumbed everyday sourdough sandwich loaf enriched with cultured butter and raw honey
Soft Sourdough Sandwich Bread (Pullman Loaf) Baker's Formula & Schedule At A Glance
The Soft Sourdough Sandwich Bread (Pullman Loaf) is formulated at 66.0% apparent hydration (yielding 69.1% true total hydration once starter water and flour are factored in), featuring 85% Unbleached Bread Flour / 15% Unbleached All-Purpose Flour, 20% active 100%-hydration levain, and 2.0% fine sea salt. Bulk fermented at 78°F (26°C) for 4 hours ~60-70% rise, followed by Pan proof at 78°F until crown domes 1 inch above tin rim, and baked at 375°F (190°C) for 38–42 minutes until internal core reaches 200°F (93°C).

Boundary Caveat: Static gram weights for Soft Sourdough Sandwich Bread (Pullman Loaf) assume 1 Pullman Loaf (1019g) at 66% apparent hydration (69.1% 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 tackinessAt 69.8% true total hydration with 8% butter lipids and 15% lower-protein all-purpose flour, long glutenin chains are lubricated by fat globules. This shortens the bite, prevents rubbery chewiness, and traps uniform micro-bubbles for an even sandwich crumb.

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 101g active levain (20% inoculation). Ferment for 4–5 hours until doubled, domed, and buoyant.
Enzymatic Autolyse & Hydration
Phase: AutolyseCombine the 505g total flour blend (85% Unbleached Bread Flour / 15% Unbleached All-Purpose Flour) with 300g 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 101g active levain, 10.1g 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 ~60-70% rise. 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 1 Pullman Loaf (950g) (1 × 950g). 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: Pan proof at 78°F until crown domes 1 inch above tin rim. 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 375°F (190°C) for 38–42 minutes until internal core reaches 200°F (93°C). 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 (69.1%): Because a 100%-hydration levain at 20% inoculation contributes equal parts water and flour, your true dough hydration is 3.1% higher than the 66.0% 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 ~60-70% rise.
Master the Handling Protocol: Lightly Oiled Bench Protocol: Use a thin film of neutral oil or softened butter on the counter during degassing and rolling rather than raw bench flour.
Verify Thermal Doneness: Bake at 375°F (190°C) for 38–42 minutes until internal core reaches 200°F (93°C) 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 66.0% apparent hydration and 69.1% true hydration in this Soft Sourdough Sandwich Bread (Pullman Loaf)?
Apparent hydration (66.0%) only divides formula water (333g) by main flour (505g). True total hydration (69.1%) includes the 50g water and 50g flour inside your 101g sourdough levain, reflecting the real physical moisture of the dough.
Q:How can I scale this Soft Sourdough Sandwich Bread (Pullman Loaf) 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 1 × 950g = 950g batch) and every flour, water, levain, and salt gram weight recalculates automatically while preserving 66.0% hydration.
Q:Why does my dough feel stickier than expected during bulk fermentation?
At 69.8% true total hydration with 8% butter lipids and 15% lower-protein all-purpose flour, long glutenin chains are lubricated by fat globules. This shortens the bite, prevents rubbery chewiness, and traps uniform micro-bubbles for an even sandwich crumb. 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.
