Cube the smoked loin. Peel the onion and cut into thin slices. Split the apricot, remove the stones and slice.
Preheat the grill pan or frying pan. Add the smoked loin cubes and fry until the cubes are brown. Add the onions and butter. Fry the onions until they are cooked and got some colour. Add the apricots to the pan. Cook over medium heat, stirring until the apricots have softened.
Add the apple cider vinegar to the hot pan and stir. Grind a lot of black pepper from the mill.
Grill the bread slices. Grate a generous layer of Appenzeller® Black Label cheese on the breads. Grill the sandwiches for a while so that the cheese melts lightly. Spoon the smoked rib apricot bake on top. Finish with chopped spring onion, mint and, if you wish, ramson.
