A balanced multigrain (Mischbrot/Mehrkorn) sourdough combining rye's depth with wheat and crunchy seeds. Long, cool fermentation improves flavor and digestibility; seeds add texture and delayed staling when toasted and presoaked[1][2].

โœ“ Mixed seeds for texture and shelf-life โœ“ Flexible schedule with overnight retardation โœ“ Techniques suitable for intermediate bakers

Ingredients

Weigh all ingredients on a kitchen scale. Use the hydration and seed percentages as a guide; adjust slightly for flour absorption differences[1].

Ingredient Amount % Note
Bread flour 300g 60% adds strength and open crumb
Medium rye flour 150g 30% for sabor and keeping qualities
Whole grain spelt or whole wheat 50g 10% adds flavor and nutrients
Water 420g 84% hydration includes presoaked seeds; adjust if seeds absorb more
Active starter (fed) 120g 24% wheat or rye-based starter, active and bubbly
Salt 12g 2.4%
Mixed seeds (sunflower, flax, sesame) 120g 24% Combine 60g soaked (sunflower/flax) + 60g dry (sesame), or adjust to preference

Schedule

Weekend Relaxed

Room-temp bulk and same-day bake

Friday 8pm Feed starter
Saturday 8am Soak seeds (if using dry seeds) (overnight)
Saturday 8:30am Mix dough (15 min)
Saturday 9am-2pm Bulk fermentation at room temp (stretch and folds as needed)
Saturday 2pm Shape and final proof (2 hours)
Saturday 4pm Bake (50-60 min)

Weekday Overnight Retard

Mix in evening, bake next afternoon

Evening 9pm Mix dough and add seeds (15 min)
Evening 9:30pm Bulk fermentation brief, then shape and place in fridge
Next day 3-5pm Remove from fridge, preheat oven
Next day 5-6pm Bake (50-60 min)

๐Ÿ’ก Tips

  • If dough ferments too quickly, retard in fridge to preserve flavors[1]
  • Seeds soaked overnight reduce competition for water during bulk and prevent dry crumb[2]

Step by Step

1

Prepare seeds and starter

Soak water-absorbing seeds (sunflower, flax) in part of the water for 30 min to overnight. Make sure your starter is active and bubbly before mixing[1].

โœ“ Visual check: Seeds plumped, starter doubled or bubbly
โš ๏ธ Common mistake: Using unripe starter โ†’ weak fermentation

โฑ 10-30 minutes depending on soak

2

Autolyse and mix

Combine flours and most of the water in a large mixing bowl. Rest 20-40 min (autolyse) to hydrate flours. After autolyse, add starter, salt, and soaked seeds, then mix using a dough scraper or dough whisk until incorporated. Autolyse helps enzyme activity and gluten development without heavy kneading[1][2].

โœ“ Visual check: Dough cohesive, seeds distributed
โš ๏ธ Common mistake: Adding salt before autolyse โ†’ slows enzymes

โฑ 25-45 minutes

3

Bulk fermentation with folds

During bulk, perform sets of stretch-and-folds every 30-45 min for the first 2 hours (3-4 sets). Allow remainder of bulk to rest until dough grows ~30โ€“50% and shows bubbles. Cover the bowl with a towel or a clear straight-sided container for monitoring[1].

โœ“ Visual check: Dough airy with gas visible at edges

โฑ 3-5 hours (depending on temp)

4

Incorporate dry seeds and shape

If using dry seeds (sesame), fold them in during the final set of folds. Turn dough onto a floured surface and pre-shape gently. Final shape into a bรขtard and place seam-side up into a floured banneton or lined bowl.

โœ“ Visual check: Evenly distributed seeds, surface tension formed

โฑ 10 minutes

5

Final proof (room temp or retard)

Proof at room temp for 1.5โ€“2.5 hours or retard in fridge 12โ€“18 hours. Cold proof improves flavor complexity and makes scoring easier[1][2].

โœ“ Visual check: Loaf puffed slightly, poke test yields slow spring back

โฑ 1.5-18 hours depending on method

6

Preheat and score

Preheat oven with a Dutch oven or cloche to 250ยฐC/480ยฐF for 30โ€“45 min. Turn loaf onto parchment paper, score with a bread lame to control oven spring. Scoring allows the loaf to expand where you want it[1].

โœ“ Visual check: Well-scored loaf, oven at temp

โฑ 30-45 minutes preheat

7

Bake

Bake covered for 15โ€“20 min to trap steam, then remove lid and lower to 200ยฐC/400ยฐF for 30โ€“35 min until crust is deep brown. Internal temp should reach 96โ€“98ยฐC (205โ€“208ยฐF) โ€” check with an instant-read thermometer[1].

โœ“ Visual check: Deeply caramelized crust, hollow sound when tapped

โฑ 45-55 minutes total

8

Cool before slicing

Transfer with oven mitts to a rack and cool at least 2 hours. Cooling completes starch gelatinization and prevents a gummy crumb[1][2].

โœ“ Visual check: Loaf no longer warm; crumb set

โฑ 2+ hours

Tips & Variations

Variations

High-seed

Increase seeds to 160g, reduce bread flour by 40g

โ†’ Denser crumb, more texture

Honey & malt

Add 1 tbsp honey and 1 tsp diastatic malt

โ†’ Improves crust color and fermentation energy

Sourdough with soaked rye flakes

Replace 30g flour with soaked rye flakes

โ†’ Chewier crumb and nutty flavor

Pro Tips

  • ๐Ÿ’ก Toast seeds briefly to deepen flavor but cool before adding to dough
  • ๐Ÿ’ก Slice with a serrated bread knife after resting; flavor develops after 24 hours[1]
  • ๐Ÿ’ก Use a dough scraper to handle sticky dough; minimal flour for shaping preserves hydration

Common Issues

If things go off-plan, check these frequent issues and fixes based on fermentation science[1][2]:

Storage

Bread box or paper bag

3-5 days

Keep cut-side down to preserve crust

Cloth wrap (linen)

4-6 days

Avoid plastic; moisture accelerates staling

Freezing

3 months

Slice before freezing and toast from frozen

โš ๏ธ Do not refrigerate โ€” cold accelerates starch retrogradation and stale flavor[2]
