The quintessential Swedish starter created by culinary icon Tore Wretman: golden butter-crisped toast piled high with creamy coldwater prawn Skagen salad, crowned with bleak roe (löjrom) and fresh dill.
Whisk mayonnaise, crème fraîche, dill, Dijon mustard, lemon juice, salt, and white pepper. Fold in dried prawns. Chill.
Melt butter in a skillet over medium-high heat. Fry bread slices until golden brown and crisp on both sides. Drain on paper towels.
Place warm toasts on plates. Top each toast with a generous dome of chilled prawn Skagen salad.
Crown each portion with a gleaming spoonful of löjrom roe, a fresh dill frond, and serve with a lemon wedge.
