For the potato snow with Carinthian char caviar, put salted water with mint and caraway seeds and boil potatoes in their skins until soft. Strain water and let potatoes steam out for 20 minutes, covered with a kitchen towel. Peel and press through a potato ricer.
Arrange in the center of the plate with the help of a fried egg ring. Mix curd cheese with sour cream and some lemon juice and put a spoonful of it on each snow. Drizzle with brown butter and place the caviar on top. Sprinkle the potato snow with Carinthian char caviar with freshly chopped herbs and season with fleur de sel.
