Put the water with the yeast and the teaspoon sugar in a mixing bowl and stir well, dissolve the yeast.
Then gradually stir in the butter and yoghurt, then add the flour with the salt and work everything into a dough and then let it rest for a good 30 minutes. Then fold the dough, press the flour on the work surface and flatten the dough, then fold it in alternately, roll out the whole thing about 10-15 times and roll out the dough and cut into eighths.
Now roll every single triangle in the grains - I have sunflower seeds, pumpkin seeds, sesame seeds and beat them briefly in the machine.
Place the pieces on a baking sheet and let rise for another 10-15 minutes. During this time, preheat the oven to 180 degrees and bake the pieces for about 30 minutes. Let these cool down - brush one or the other with butter and jam to taste - then freeze the rest.
* Tip! I used wholegrain spelled in my recipe, but the parts were a bit stiff as a result, I recommend spelled flour type 630, if you try it ... I ask for feedback and I'm happy to provide a picture (s). Have fun baking
