At a Glance
Frankenlaib is a traditional Franconian rye sourdough loaf: moist crumb, pronounced rye flavor and good keeping. Use a young, stiff rye starter or fed levain to control acidity and enzyme activity — this prevents a gummy crumb and excessive sourness [5][3]. Long, cool proofing develops flavor while limiting amylase-driven stickiness in rye doughs [4][2].
Not suitable if:
- • You've never baked sourdough before → start with the beginner recipe
- • You don't have an active rye starter → create a starter

Ingredients
Weigh all ingredients on a kitchen scale. Rye is sensitive to hydration and enzyme activity; grams give repeatable results [2][5].
| Ingredient | Amount | % | Note |
|---|---|---|---|
| Medium rye flour (Type 1150) | 500 g | 100% | Traditional Frankenlaib uses high-ash mid-to-dark rye |
| Water | 425 g | 85% | Room temp (approx. 20–24°C). High hydration accounts for rye pentosans holding water [2] |
| Active rye starter (stiff or 1:1:1 fed) | 200 g | 40% | Use 8–12 h after feeding; a young levain limits excessive acidity [5][7] |
| Salt | 12 g | 2.4% | Important for flavor and enzyme control [3] |
| Caraway (optional) | 1 tsp (2 g) | 0.4% | Traditional aroma for Frankenlaib |
Schedule
Traditional (flavor-first)
Build levain, long bulk, cold final proof.
Fast weekend
Shorter, warmer ferment with attentive timing.
💡 Tips
- If fermentation seems too fast, cool the dough — cold slows amylase and bacterial activity and preserves structure [3][5].
- Shaped loaves keep well 24–48 h in the fridge before baking; this is common for Frankenlaib [2][7].
Step by Step
Prepare levain (optional for flavor control)
If using a levain, mix a portion of your rye starter with fresh rye flour and water to build activity 6–12 h before mixing the dough. Aim for a levain that's active but not over-ripe to limit excessive acidity that weakens rye structure [5].
⏱ 6–12 hours
Mix dough
Combine rye flour and most water in a large mixing bowl to hydrate fully (autolyse). After 20–30 min add starter/levain and remaining water plus salt. Mix with a dough scraper or dough whisk until homogeneous — rye won't develop the same gluten but must be evenly hydrated [1][2].
⏱ 10–15 minutes
Bulk fermentation
Cover the bowl (lid, towel, or proofing box) and ferment at 20–22°C. Rye doughs show less volume increase; look for a 40–60% rise, surface doming and gas holes. Avoid temperatures above 25°C — too warm accelerates amylase and can make the crumb gummy [3][2].
⏱ 4–8 hours
Shape into Frankenlaib
Flour work surface with rye or rice flour. Turn dough out using a dough scraper — wet hands help manage sticky dough. Shape gently into an oblong; avoid tightening seams excessively. Place into a floured banneton seam-side up.
⏱ 8–12 minutes
Final proof (cold preferred)
Cover and refrigerate for 12–20 hours. Cold proofing develops flavor, controls acidity, and reduces enzymatic breakdown that causes gummy crumb [3][5]. If proofing at room temp, limit to 1.5–3 hours and monitor.
⏱ 12–20 hours (fridge) or 1.5–3 hours (room temp)
Bake
Preheat oven to 250°C/480°F with a preheated Dutch oven or baking stone inside. Turn loaf onto parchment paper or floured peel, score with a bread lame — scoring controls expansion since rye doesn't form high ears — and bake covered 15–20 min, then uncovered at 200°C/400°F for 35–45 min until deep mahogany crust [1][4].
⏱ 50–70 minutes
Cool thoroughly
Transfer loaf using oven mitts to a rack and cool 2–4 hours. Cutting too early traps moisture and yields gummy crumb — patience is critical for rye breads [2][5].
⏱ 2–4 hours
Tips & Variations
Variations
Seeded Frankenlaib
Add 60 g mixed seeds (sunflower, pumpkin) folded in during final mix
→ Creates more texture and improves shelf stability
Caraway & Coriander
Use 1 tsp caraway and 1/2 tsp crushed coriander in dough
→ Traditional Franconian aroma; complements rye tang [6]
Lower hydration (firmer crumb)
Reduce water to 375 g (75% hydration)
→ Easier handling and slightly denser crumb
Pro Tips
- 💡 Always measure by weight with a digital kitchen scale — small water changes hugely affect rye behavior [2].
- 💡 If dough sticks to hands, wet them: wet-hand shaping is an established technique for rye [5].
- 💡 Dust banneton with rice flour to avoid sticking when transferring to the oven [4].
Common Issues
Common issues and quick fixes:
Storage
Paper bag or bread bag at room temp
5–7 days
Keep cut side down to retain moisture
Kitchen towel
3–4 days
Wrap in linen to let crust breathe
Freezing
3 months
Slice and freeze; toast slices from frozen
⚠️ Don't store bread in the fridge — rye stales faster due to starch retrogradation at cool temperatures [3][2].
