Preheat the oven to 180 degrees.
Mix eggs and sour cream in a large bowl.
Add sugar, flour and raisins to the mixture and stir until all ingredients combine well.
Take a large non-stick pan (make sure the pan can go to the oven!!) and fry the mixture on butter on very low heat (3 out of 10) from both sides. Each side about 5 minutes.
Take the Kaiserschmarrn of the heat and if you like the dessert extra sweet and crispy cover it with a thin layer of powdered sugar. After this put the pan in the oven and bake the mixture in oven until done (another 8-10 minutes). Do not use any lid.
Remove the pan from the oven and but the mixture into 3-4cm long pieces. Add another layer of powdered sugar and place plum preserves or apple sauce on the side. Ice cream go also very well with this dish!
