1. Shred Pumpkin Seeds

Weight Ingredient
50 g Pumpkin seeds
  • Shred the pumpkin seeds until they are finely shredded like whole wheat flour
  • Using a blender or grinder is pretty much the best way to do it

2. Mix

Weight Ingredient
300 g Mature sourdough starter – From whole spelt flour
400 g White spelt flour
110 g Rye flour
15 g Salt
10 g Sugar
3 g Yeast – Fresh (optional)
20 g Honey
310 g Water – 20°C (68°F)
50 g Shredded pumpkin seeds
  • Mix all of the mentioned ingredients in a stand mixer for 3 minutes on speed level one and 6 minutes on speed level two
  • The dough should be smooth after mixing and not stick to the bowl a lot

3. Bulk Fermentation, Stretch & Fold

  • Cover the dough and let it rest for a total of 2,5 hours at 20-22°C (68-71,6°F)
  • During that time stretch & fold the dough every 30 minutes (3 times in total) and after the 3rd time, let it ferment further for 1 hour until 2,5 hours are reached in total
  • After each stretch and fold put it back to the bowl and cover it again so it doesn’t dry out

4. Pre-shape

  • Get the dough in shape by roughly rounding it
  • Afterwards look for a dry spot on your surface and flour it
  • Transfer the pre-shaped dough ball on the floured surface
  • Cover it with a towel and let it rest for 20 minutes
  • Tip: If you realize that the dough starts sticking to your hand or bench knife, just clean the bench knife of any dough and flour it a bit again

4. Shape

  • Shape your dough by rounding it
  • Afterwards dip your hands in water and damp the top and sides of the dough with them
  • Now take the pumpkin seeds and press them all over the top and sides of the dough

5. Proof

  • Dust your proofing basket with all-purpose flour
  • Put your previously shaped dough seam-side-up in the dusted proofing basket
  • Add flour on top and cover it with a towel
  • Let it proof for 2,5 hours at 20-22°C (68-71,6°F)
