A rustic Roggenbrot enriched with toasted pumpkin seeds (Kürbiskerne). The recipe uses a seed soaker to prevent bitterness, increase hydration and extend shelf life. Techniques are adapted for high-rye doughs, prioritizing acid balance and gentle handling to avoid gummy crumb and collapse [1][2][10].

✓ Seed soaker (Quellstück) prevents bitter or oily seeds ✓ Cold retard develops flavor and helps handling ✓ No intensive kneading — suitable for intermediate bakers

Ingredients

Weigh all ingredients on a kitchen scale. For rye breads, accuracy and baker's percentages matter more than volume [3][6].

Ingredient Amount % Note
Medium rye flour 360g 60% Type comparable to German 997–1150
Bread flour (or strong wheat) 240g 40% Adds gluten for structure
Water (total) 420g 70% Portion used for seed soaker included
Active rye starter (100% hydration) 150g 25% Fed and active 6–12h after feeding
Salt 12g 2%
Pumpkin seeds (Kürbiskerne) 120g 20% Toast or soak per soaker instructions below

Schedule

Weekend Version

Build flavor with cold retard and bake when relaxed

Friday evening Toast seeds (optional) and start seed soaker
Saturday 8am Feed starter
Saturday 4pm Mix dough (including soaked seeds) (20 min)
Saturday 4:30–9pm Bulk fermentation at 20–24°C (4–5 hours)
Saturday 9pm Shape and place in banneton, into fridge (cold retard)
Sunday midday Bake (60–70 min)

Weekday Version

Mix in the evening, cold-proof overnight, bake next evening

Evening 8pm Mix dough and bulk ferment (shortened)
Evening 10pm Shape and refrigerate overnight
Next day evening 6pm Preheat and bake (60–70 min)

💡 Tips

  • If bulk fermentation accelerates, move shaped loaf to fridge to slow activity [3].
  • Shaped dough keeps well 24–48h refrigerated; this also improves scoring and flavor [10].

Step by Step

1

Prepare seed soaker (Quellstück)

Combine pumpkin seeds with 80g of the recipe water (hot or boiling water for a scalded soaker). Let soak 1–3 hours or overnight in a covered jar to hydrate and deactivate lipase that can make seeds bitter. Drain excess if much remains; keep seeds and soaking liquid for dough to retain flavor and hydration [1][10].

✓ Visual check: Seeds plump and slightly soft; no hard cores
⚠️ Common mistake: Skipping soaking → oily or bitter seeds, uneven hydration

⏱ 1–12 hours

2

Mix flours and water (autolyse)

In a large mixing bowl combine all flours and most of the water (reserve ~40g). Mix until no dry flour remains and rest 30–60 min. Autolyse helps enzyme activity in rye without mechanical kneading [6].

✓ Visual check: Flours fully hydrated, dough cohesive but sticky
💡 Use a dough whisk or spoon for mixing if preferred

⏱ 30–60 minutes

3

Add starter, salt, and soaked seeds

Add active starter, salt, and the hydrated pumpkin seeds (and soaking liquid if kept). Mix thoroughly with a dough scraper until incorporated. Rye dough will be sticky and looser than wheat dough — that's normal [2][6].

✓ Visual check: Seeds evenly distributed, dough uniform
⚠️ Common mistake: Over-flouring to reduce stickiness → leads to dry crumb

⏱ 5–8 minutes

4

Bulk fermentation

Cover dough and bulk ferment at 20–24°C. For higher rye content expect less visible rise; rely on surface doming and small bubbles. Perform 2 gentle stretch-and-folds (wet hands) during the first 60–90 minutes to orient gluten and evenly distribute seeds [2][3].

✓ Visual check: Slight volume increase (~30–50%), small bubbles

⏱ 4–6 hours (varies)

5

Shape and final proof (cold retard recommended)

Flour banneton generously with rye flour. Turn dough onto a floured surface using a dough scraper. Shape gently into an oblong or round and place seam-side up in the banneton. Refrigerate 12–24 hours for flavor and easier scoring [10][6].

✓ Visual check: Loaf slightly puffed in banneton; surface not collapsed

⏱ 1.5–2 hours at room temp or 12–24 hours in fridge

6

Bake with steam

Preheat oven to 250°C/480°F with your Dutch oven or cast iron pot inside for 30–45 minutes. Turn loaf out onto parchment paper, score with a bread lame, transfer to the pot, cover and bake 15–20 min. Remove lid, reduce to 200°C/400°F and bake another 35–45 min until crust is deeply browned. Check internal temperature with an instant-read thermometer: aim for 96–98°C / 205–208°F [4][10].

✓ Visual check: Deep brown crust, hollow sound when tapped

⏱ 50–65 minutes

7

Cool fully

Remove loaf with oven mitts and cool on a rack at least 2 hours — ideally until fully room temperature. Cutting earlier traps moisture and yields gummy crumb in rye breads [6][2].

✓ Visual check: Loaf cool to touch and firm crumb

⏱ 2+ hours

Tips & Variations

Variations

Toasted-seed crust

Brush loaf with water and roll in toasted pumpkin seeds before final proof

→ Crunchy exterior and extra seed aroma

Mixed seeds

Replace half the pumpkin seeds with sunflower seeds (50g each)

→ More complex texture and nuttiness

Stronger lift

Increase bread flour to 50% and reduce rye to 50%

→ Looser crumb, more oven spring (less authentic Roggenbrot)

Pro Tips

  • 💡 Always soak seeds or roast briefly; unsoaked raw seeds can release oil and taste bitter over time [1].
  • 💡 Use a serrated bread knife to slice cooled bread — the crumb continues to set after baking.
  • 💡 If dough is too sticky to handle, chill briefly (15–30 min) rather than adding flour.

Common Issues

Common issues and quick fixes when baking Roggenbrot with seeds:

Storage

Bread box or paper bag

5-7 days

Keep loaf whole; cut side down once opened

Cloth or linen bag

3-4 days

Allows breathable storage to preserve crust

Freezing

3 months

Slice and freeze; toast or warm slices from frozen

⚠️ Do not store bread in the fridge — refrigeration accelerates staling through starch retrogradation [6].
