You can also add sour cream to the "Skagenröra" to accompany the mayonnaise, but be careful not to let excess liquid get into the mixture. Make sure you dry the prawns really well. Otherwise the Skagen may become loose and not stay on the bread. Try the Skagen salad with baked potatoes as well.
Prepare the prawn or shrimps. Frozen shrimps can be rinsed in cold water and dried on kitchen paper. You can also use lemon juice to cook the prawns raw. It is important that the shrimps you use is well dried so that the skagen does not become watery.
Put butter on pan and toast the breads nicely brownish.
Peel and chop the onion as finely as you can. Finely chop the dill.
Mix the sauce ingredients. Leave some dill for garnish.
Stir the red onion slices (also leave some for garnish) and the shrimps into the sauce as well and turn over a couple of times.
Cut the edges off the toasted bread and put one per plate. Top with shrimps and garnish with roe, onion and dill.
Enjoy the Toast skagen immediately, so the bread doesn't become soggy.
