I try to keep the semla away from the bow, as the grease would ruin the hair, but some rosins would definitely make a good replacement for the powdered sugar on top of the semla. Not this one, though; it's of the sticky kind. Maybe I could replace the almond paste in the middle with some of it, though...
By the way, just thinking of semlor makes me happy.
Too bad it's not the right season for them...
