This is my version of smorrebrod, which is a Scandinavian open-faced sandwich, and translates to "buttered bread," so what’s not to like? It can be topped with anything from cold cuts, pieces of meat or fish, cheese, spreads…all that good stuff. Mmm!
Melt a thin layer of butter in a skillet over medium heat, then add the bread and toast on both sides until golden, 2 to 4 minutes per side. Combine the sour cream, preserved lemon and a few turns of pepper in a small bowl.
To assemble, dollop the preserved lemon sour cream all over the bread, then top with slices of avocado. Season the avocado with salt. Nestle in the slices of salmon, radishes and cornichons. Top with black pepper and crushed red pepper, if using. Sprinkle with the chives or dill and sesame seeds, then serve with the lemon wedges. Enjoy!
