Biff Rydberg (Beef Rydberg - Delicious Beef and Potato Dish)

You only need one pan to prepare this delicious meal. This dish probably originated at the swanky Hotel Rydberg in Stockholm - something of a Swedish Algonquin, a magnet for the glitterati - actors and artists of all stripes. This is supposed to be served with Senapsgrädde (Mustard Cream Sauce). Enjoy!

Ingredients

• 1  lb beef tenderloin, cut into bite-sized cubes

2. Heat 2 tablespoons butter in skillet, add onions. Sauté until onions are transparent. Remove from skillet and set aside.
3. Salt and pepper meat to taste. Increase heat to high heat, and add meat to skillet. Brown meat, stirring frequently, until meat is browned on the outside, but still pink inside.
4. Arrange on a platter with potatoes on one side, meat on the other, divided by the onions. Garnish with chopped parsley and worcestershire sauce. Serve with mustard cream.
