Warm buttermilk, salt and syrup lukewarm. Mix the yeast first with something, then with the whole milk mixture
Mix flour, coarse meal, linseed, sesame and sunflower seeds. Add to the buttermilk-yeast mixture and knead well with the dough hooks of the hand mixer
Pour the dough into a greased, flour-spread box form (approx. 25 cm long). Bake in the preheated oven (electric cooker: 175 °C / convection oven: 150 °C / gas: level 2) for about 2 hours. Allow to cool and turn over
The bread tastes best fresh. So: eat it quickly or freeze it!
