I have discovered a recipe that needs no kneading or sourdough, just 0.5 kg yoghurt: translatef from here

ingredients

• 25g fresh yeast or half package dry yeast
• 300g water
• 75g sunflower seeds
• 50g linseed
• 200g crushed rye seeds (can be replaced with oat kernels)
• 375g rye flour
• 500g yoghurt naturel
• 75g wheat flour
• 12.5g salt

TODO:

• dissolve yeast in water
• add seeds, salt and yoghurt, mix
• add the flour and mix well
• let ferment for 1h
• put in 1.5 litre bread pan
• let rise 30m
• heat oven to 200C (390F)
• Put in bread, and lower temperature in oven to 160C (320F)
• Let bake for 1h15m (I added 15m)
