Classic German-style sourdough rolls enriched with toasted sunflower seeds for crunch and flavor. The formula emphasizes a moderate hydration dough for an open but roll-shaped crumb. Long, cool fermentation improves flavor and digestibility[1][2].

Ingredients

Weigh ingredients on a kitchen scale. Use the hydration and seed percentages as a guide to adjust for your flour.[1][2]

Ingredient Amount % Note
Strong bread flour 600g 100% High-protein for structure
Water 390g 65% Room temperature for standard fermentation
Active levain (100% hydration) 120g 20% Peak activity, 4-6 hours after feeding
Salt 12g 2%
Sunflower seeds (dough) 100g 17% Folded into dough
Sunflower seeds (topping) 60g 10% Soaked briefly or toasted for adhesion/flavor
Olive oil 10g 1.7% Optional for softer crust

Schedule

Morning Bake (same-day)

For a same-day bake with active starter

6:30 AM Feed starter
9:30 AM Mix dough (autolyse included) (20 min)
9:50 AM - 12:30 PM Bulk fermentation with 3 sets of stretch-and-folds (3 hours)
12:30 PM Pre-shape and bench rest (20 min)
1:00 PM Final shape and proof (room temp) (1-1.5 hours)
2:30 PM Bake (18-22 min)

Overnight Fridge Proof (weekday)

Mix in the evening, bake next morning

9:00 PM Mix dough and do 1 stretch-and-fold (15 min)
9:15 PM Divide and shape loosely, place on tray in fridge
Next day 7:00 AM Preheat oven and finish proof on counter
7:45 AM Bake (18-22 min)

💡 Tips

  • If bulk fermentation is progressing quickly, move shaped rolls to the fridge to slow proofing[1].
  • Rolls can overproof quickly on warm days—watch size and the poke test rather than the clock[2].

Step by Step

1

Autolyse and mix

Combine flour and water in a large mixing bowl. Mix until no dry flour remains. Rest 20–30 minutes (autolyse) to hydrate the flour and begin gluten development[1]. After autolyse, add levain and salt, mix until incorporated.

✓ Visual check: Dough is cohesive and slightly tacky
⚠️ Common mistake: Skipping autolyse → weaker dough and slower fermentation

⏱ 25-35 minutes

2

Add seeds and bulk ferment

Fold in 100g sunflower seeds using a dough scraper or wet hands so seeds are evenly distributed. Perform 3 sets of stretch-and-folds during the first 90 minutes of bulk fermentation to build strength[1][2].

✓ Visual check: Dough shows windowpane-like extensibility and bubbles
💡 Toast seeds quickly for extra flavor before folding in

⏱ 90-180 minutes (depends on temp)

3

Divide and pre-shape

Turn dough onto a lightly floured surface or semolina. Use a dough scraper to divide into 12 equal pieces (~70g). Pre-shape into rounds and rest 15–20 minutes uncovered.

✓ Visual check: Tension forms around each round

⏱ 20-25 minutes

4

Final shaping and topping

Gently shape rounds into smooth rolls. Lightly brush or spray with water and press tops into a tray of sunflower seeds so they adhere. Place rolls on a parchment-lined tray (parchment paper) or proofing cloth.

✓ Visual check: Seeds cling to tops, rolls have surface tension
💡 For rustic look, score each roll with a shallow cross using a bread lame

⏱ 10 minutes

5

Final proof

Proof at room temperature until rolls are noticeably puffy (poke test: indent springs back slowly). For overnight option, cover and place tray in fridge for 8–14 hours then finish proof at room temp for 30–60 minutes before baking[1][2].

✓ Visual check: Puffy, jiggly rolls ready to bake

⏱ 45-90 minutes (or overnight in fridge)

6

Bake

Preheat oven to 240°C / 465°F with a tray or stone inside for 30 minutes. Transfer rolls on parchment paper to hot surface, introduce steam (spray or pan of water) and bake 8 minutes. Reduce to 210°C / 410°F and bake another 10–14 minutes until golden and crisp[1].

✓ Visual check: Golden crust, internal temp around 98–100°C / 208–212°F

⏱ 18-22 minutes

7

Cool

Cool rolls on a wire rack for at least 30 minutes to set crumb. Cutting too soon leads to a gummy texture[2].

✓ Visual check: Crust crisp, crumb set

⏱ 30+ minutes

Tips & Variations

Variations

Mixed seeds

Use equal parts pumpkin, sesame and sunflower seeds for topping

→ More complex texture and flavor

Whole grain mix

Replace 150g bread flour with whole wheat

→ Heartier flavor, slightly denser crumb

Cheesy rolls

Add 80g grated hard cheese into dough

→ Savory, great for sandwiches

Pro Tips

  • 💡 Measure with a kitchen scale — small weight differences change roll texture[1].
  • 💡 Use a dough scraper to portion neatly and keep hands cleaner.
  • 💡 Let rolls cool adequately — flavor continues developing after bake[2].

Common Issues

If things go off-plan, check these common issues:

Storage

Room temp in bread bag

2-3 days

Re-crisp in oven at 180°C / 350°F for 5–8 minutes

Paper bag

1-2 days

Keeps crust crisper but crumb dries faster

Freezing

3 months

Freeze after cooling, reheat from frozen at 160°C / 320°F for 10–12 minutes

⚠️ Avoid long-term fridge storage — it speeds staling due to starch retrogradation[2].
