This recipe is universal, but the best one I had was in Emden, in a restaurant called Hafenhaus. The chef offers that as an appetizer. It was just perfect. I am not giving any quantities, you can add the ingredients based on your taste. On my facebook page Delicioso y Divertido, I asked my audicence, what I could fix with rosemary. This recipe was very popular!
Red potatoes, boiled, with skin.
salt and pepper. Best with Kosher salt.
