Lingonberry jelly is traditionally used with Swedish meatballs; you can substitute cranberry, red currant or raspberry jelly if you can't find lingonberry jelly.
Ingredients
Meatballs:
1 large yellow or white onion, peeled, grated (through a cheese grater)
2 Tbsp butter
2/3 cup milk
4-5 slices of bread, crusts removed, bread cut into pieces
2 eggs
1 pound ground pork
1 1/2 pounds ground beef
2 teaspoons salt
1 teaspoon freshly ground nutmeg
1 teaspoon ground cardamom
2 teaspoons black pepper
Sauce:
6 Tbsp butter
1/3 cup flour
1 quart beef stock
1/2 to 3/4 cup sour cream
Salt
2 to 4 Tbsp of Lingonberry, cranberry, red currant or raspberry jelly, more or less to taste (optional)
Method
1 Sauté the grated onion in the butter over medium-high heat until the onions soften and turn translucent, about 3-4 minutes. Remove from heat and let cool.
2 In a medium bowl, mix the bread pieces with the milk. Set aside for 15-20 minutes, or until the bread soaks up all the milk. When it does, pulverize the bread in a food processor and pour it into a large bowl.
3 Add the cooled onions to the bowl of milk and bread. Add the rest of the meatball ingredients - eggs, ground pork, ground beef, salt, nutmeg, cardamom, pepper. Using your (clean) hands, mix well for about 2 minutes until the ingredients are well combined.
4 Use a tablespoon to measure out the meat for the meatballs. As you form the meatballs, set each one aside on a sheet pan or plate. You should get 40 to 50 meatballs.
