Kastenweißbrot is a closed-top tin loaf made with sourdough. Using a young, active starter and modest hydration yields a fine, soft crumb with mild acidity—ideal for sandwiches.[1][5][7] This recipe focuses on predictable fermentation and simple shaping for consistent slices.

✓ Gentle gluten development via autolyse and folds ✓ Options for same-day or overnight schedules ✓ Designed for loaf tins or lidded Pullman-style tins

Ingredients

Weigh all ingredients on a kitchen scale. Precision and temperature control are the most important variables for consistent tin loaves.[3][5]

Ingredient Amount % Note
Bread flour (strong wheat) 700g 100% High-protein flour gives structure for slicing
Water 500g 71% Room temperature; adjust ±10g to reach tacky but manageable dough
Active sourdough starter (100% hydration) 200g 29% Ideally doubled 4–6 hours after feeding
Salt 14g 2%
Butter (soft) 25g 3.5% Optional—adds tenderness and shelf life (classic in Pullman)
Milk (optional, warm) 30g 4.3% Replace equal water for richer crumb

Schedule

Same-day (active) schedule

For a weekend morning bake with a lively starter

06:00 Feed starter
09:00 Starter peaked → mix dough (15 min (incl. autolyse))
09:15-13:15 Bulk fermentation with 3 sets of coil folds every 30 minutes initially (4 hours (depends on temp))
13:15 Shape and place in greased tin (10 min)
13:30-15:00 Final proof at room temp (or retard in fridge for 8–12h) (1.5 hours)
15:00 Bake (40–60 min)

Overnight retard (weekday)

Mix in evening, bake next morning for convenience and flavor

21:00 Mix dough and perform initial folds (15 min)
21:30 Shape, place in tin, refrigerate overnight (10 min)
Next morning 07:00 Remove from fridge, allow to warm 1–2 hours (60–90 min)
08:30 Bake (40–60 min)

💡 Tips

  • If dough is proving too fast, slow it by refrigerating (cold retards yeast and bacteria activity)[2][6].
  • Shaped dough can stay 24–48h refrigerated — flavor increases and final shaping tension improves sliceability.[5][7]

Step by Step

1

Autolyse & mix

Combine flour and water in a large mixing bowl. Autolyse 20–30 minutes to hydrate the flour and begin gluten development. Add starter and salt (dissolve salt in a little water first if preferred). Mix until cohesive using a dough scraper.

✓ Visual check: Dough should be smooth, slightly tacky, and hold shape
⚠️ Common mistake: Overmixing early—autolyse reduces need for intense mixing

⏱ 20–30 minutes (autolyse) + 5–10 minutes mixing

2

Strengthen the dough

Develop gluten with 3 sets of coil folds or stretch-and-folds during the first 90 minutes of bulk fermentation. Rest between folds to relax the dough. Incorporate butter at the end of the folding sequence if using.

✓ Visual check: Dough shows a smoother surface and windows with some extensibility
💡 Use wet hands to prevent sticking during folds

⏱ 1.5–3 hours (part of bulk fermentation)

3

Bulk fermentation

Cover the bowl and ferment at 21–24°C (70–75°F). Look for ~30–50% volume increase and bubbles at the surface. Avoid overproofing—young levain yields softer crumb and less acidity which is desirable for tin loaves.[1][4]

✓ Visual check: Dough slightly domed with small bubbles

⏱ 3–5 hours (variable)

4

Shape for tin

Degas gently and pre-shape into a cylinder. Rest 15 minutes. Final shape into a tight log that fits your loaf tin (standard 30cm Pullman or 25x10cm loaf tin). Grease tin with butter or oil, or line with parchment. Transfer dough seam-side down into tin. If you used a banneton for shaping, flip the dough into the greased tin.

✓ Visual check: Tension across the top; loaf length fits tin snugly

⏱ 10–15 minutes

5

Final proof

Cover the tin and proof until the dough reaches about 80–90% of the tin height. For a mild sour flavor and tender crumb, avoid long warm proofing; instead retard in the fridge for flavor if desired.[5][7]

✓ Visual check: Poke test: a slight indentation that springs back slowly

⏱ 1–2 hours at room temp or 8–18 hours in fridge

6

Bake

Preheat oven to 230°C/450°F. If using a cloche or Dutch oven approach for steam, preheat with the vessel inside. Place tin in the oven; if you want a closed-top Pullman, place the lid on after a brief initial spring. Bake 30–40 minutes until crust is golden and internal temperature reaches 96–98°C (205–208°F) measured with an instant-read thermometer. For open-top tins, tent with foil if browning too quickly.

✓ Visual check: Even golden crust and internal temp reached

⏱ 30–45 minutes

7

Cool & rest

Remove loaf from tin and cool on a wire rack for at least 2 hours before slicing. Slicing too early gives a gummy crumb — the starches need to set.[3][5]

✓ Visual check: Loaf cooled to room temperature

⏱ 2+ hours

Tips & Variations

Variations

Slightly sweeter Pullman

Add 1–2 tbsp honey or sugar to the dough

→ Softer, browner crust and milder flavor

Milk & butter enriched

Replace 30g water with milk and keep 25g butter

→ Richer crumb, stays soft longer

Whole-wheat mix

Replace up to 20% of flour with whole wheat and increase water by 5–10g

→ More flavor, slightly denser crumb

Pro Tips

  • 💡 Grease tins with butter or use parchment to prevent sticking; press a little rice flour into buttered surface for extra non-stick behavior.[4]
  • 💡 Use a bread lame or sharp knife to score if baking open-top; for Pullman, a straight seam is fine.
  • 💡 After baking, cool completely before slicing with a serrated bread knife for clean, even slices.

Common Issues

Common problems and quick fixes:

Storage

Room temperature in bread bag or box

3–5 days

Store cut side down to slow drying

Cloth-wrapped

3 days

Wrap in linen to maintain crust softness

Freezing

3 months

Slice and freeze; reheat slices directly from frozen

⚠️ Avoid refrigeration — it accelerates staling through starch retrogradation.[3]
