A semla, for those of you who don’t know, is a wheat bun filled with almond paste and absurd amounts of whipped cream. Historically they were eaten only on Shrove Tuesday (today,) the first day of Lent, but are now available in Sweden from around Christmas until Easter as a sort of national snack. But today is The Official Semla Day.
