A perennial fixture of the Polish zakąski buffet: hard-boiled farm eggs halved and crowned with a dollop of creamy chive mayonnaise, sweet paprika, and fresh dill sprigs.
Slice the peeled hard-boiled eggs neatly in half lengthwise with a sharp, wet knife so the golden yolks remain intact.
In a small bowl, whisk together the mayonnaise, sharp table mustard, and sour cream until silky. Season with a pinch of sea salt and black pepper.
Arrange the egg halves yolk-side up on an elegant starter platter. Spoon or pipe a generous rosette of the seasoned mayonnaise over each yolk.
Dust the mayo crowns lightly with sweet paprika. Scatter with finely chopped fresh chives and garnish each half with a delicate dill sprig before serving.
