What about this? I did not used syrup and I got all the hard components + seeds overnight in a bowl with water (vatten, yes!).
As for the rest:
Råg = rye
Vete= wheat
Solros = sunflower
Linfrö = flaxseed
flaxseedI added pumpkin seeds, chia, sesame, and it was mentioned that cumin would be a good addition.
