This Scandinavian classic, based off a recipe by Magnus Nilsson, is a versatile showstopper that’s amazing on its own or as part of your seafood spread. Eat it as is, with a squeeze of lemon, or create a multitude of hors d’oeuvres. It makes an epic bagel too with a smear of cream cheese topped with capers, thinly sliced red onion and dill leaves
