Biff a la Lindstrom (Hamburgers a la Lindstrom)

• 1 tablespoon butter
• 2 tablespoons onions finely chopped
• 1 pound ground beef, lean
• 4 large egg yolks
• 1 tablespoon capers drained and finely chopped
• 1 1/2 teaspoons salt
• 1 x black pepper freshly ground
• 1 teaspoon vinegar white
• 1/2 cup heavy whipping cream
• 1/4 cup beets cooked fresh or canned, drained and finely chopped
• 2 tablespoons butter
• 2 tablespoons vegetable oil
• 4 large eggs fried, optional

1. In a small pan, melt the 1 tablespoon of butter.
2. When the foam subsides, add the onions and cook for 2 or 3 minutes or until they are soft and transparent, but not brown.
3. Scrape into a large bowl and add the meat, egg yolks, capers, salt, pepper and white vinegar.
4. Mix together and moisten with the heavy cream.
5. Then stir in the drained chopped beets.
6. Shape the mixture into 12 to 14 round partties, about 2 to 3 inches in diameter.
7. In a heavy large skillet, heat the butter and oil.
8. When the foam subsides, add the patties 3 or 4 at a time and cook over moderately high heat for 5 to 6 minutes on each side or until they are a deep brown.
9. In Sweden, these spicy hamburgers are frequently served with a fried egg set atop each, in which case they are made larger and thicker.
