INSTRUCTIONS
1. Melt 2 tablespoons of the butter in a small sautee pan over medium heat, add the finely diced onion, and sautee until softened and any liquid it releases has evaporated, about 2 minutes. Set aside to cool
2. completely.
3. Combine the cooked and cooled onion with the pork, beef, eggs, egg yolks, scallions, soaked bread, and parsley in a large bowl, season with salt and pepper, and mix thoroughly but gently with clean hands. Using slightly damp hands, shape the mixture into meatballs, about the size of golf balls (or larger if preferred).
4. Bring the stock to boil in large saucepan over high heat, reduce the heat to low, low and maintain the stock at a simmer. Drop the meatballs gently into the stock and cook until they are completely cooked, about 7 to 10 minutes. (They will float to the top when done, but if you're still not certain, remove a meatball and cut it open.) Remove the meatballs with a wire mesh skimmer or slotted spoon and set aside momentarily. (If you wish, the stock and meatballs may be refrigerated at this point
5. and the dish finished later.)
6. Bring the stock again to a boil over high heat and boil until reduced by half (to about 4 cups). Strain through a fine mesh strainer and set aside.
7. Melt the remaining 3 tablespoons of butter in a large sautee pan over medium heat, add the coarsely chopped onion, and sautee until softened and translucent. Add the garlic and sautee for another minute until softened. Sprinkle in the flour, stirring to incorporate (making a roux). Cook for about 1 minute, and remove from the heat.
8. Whisk the reduced stock into the roux, making sure the sauce is free of lumps. Bring to a boil over high heat, reduce the heat to medium, and simmer until the sauce is thick enough to coat the back of a spoon. Season with white pepper and additional salt if necessary, strain through a fine mesh strainer, and return the sauce to the sautee pan.
9. Place the meatballs in the sauce, stir in the cream, capers and brine, and parsley, and simmer over low heat for about 10 minutes.
10. Serve the meatballs over a platter of white rice.
