a special treat for Easter - classic Swedish "dammsugare". The name means "vaccum cleaners", and that's a very strange name for a cookie indeed. The reason? Well, traditionally these are made with lime-green marzipan and chocolate dipped ends, and maybe there was an early vaccum cleaner model that looked like that..? I really don't know, and there doesn't seem to be a simple answer out there, so it'll have to remain a mystery.
And it has many names, "dammsugare" just happens to be most widely used one. "Punschrulle" is also quite common, getting it's name from the liqueur used to flavor the filling. Punsch, as I've written before, is made from arrak and very sweet. If you can't find it, try using something like Amaretto or Frangelico instead - won't be the same, but it'll be really good.
