The Semla is a sweet wheat flour bun flavored with cardamom and filled with almond paste and whipped cream.
How to eat semla like a local (according to visitsweden.com):
Start with the lid. Use it to scoop up some of the gooey contents. Proceed with the rest of the bun. The carnal eat it shamelessly straight from hand-to-mouth. The refined like to fork-it. Bohemians do it with a spoon. Tourists do it with confusion. And traditionalists order it in a bowl of warm milk. All are equally good.

Just about every café and supermarket will offer Semla during February 13st and the whole week.
