- 4 slices dense rye bread (about 8 oz / 225 g total) - 4 tbsp (57 g) unsalted butter, softened - 4 smoked herring fillets, approx. 3 oz (85 g) each (preferably Bornholm-style smoked herring) - 4 egg yolks, approx. 0.6 oz (18 g) each - 1 small red onion, thinly sliced (about 4 oz / 115 g) - 2 tbsp (8 g) finely chopped chives - Coarse sea salt, to taste - Freshly ground black pepper, to taste
1. Lightly toast the rye bread slices until crisp at the edges, then spread each slice with about 1 tbsp (14 g) softened butter. 2. Arrange one smoked herring fillet on each buttered slice. Top each fillet with a few thin rings of red onion. 3. Carefully place one raw egg yolk in a small cup and gently transfer a yolk onto the center of each sandwich so it sits atop the herring (keep yolks whole). 4. Sprinkle chopped chives over each sandwich, season with a pinch of coarse sea salt and a grind of black pepper, and serve immediately so the yolk remains runny and mixes with the fish when pierced.
