Albondigas (Spanish Meatballs)
From America’s Test Kitchen
For the meatballs:
  1. In a large bowl, mash the bread and milk together to form a smooth paste. Add the ground meats, Manchego, parsley, yolk, garlic, salt, and pepper to the mashed bread and mix until uniform. Shape the mixture into 1/2-inch-round meatballs (1 teaspoon per meatball; you should have 35 to 40 meatballs).
  2. Heat the oil in a 12-inch nonstick skillet over medium-high heat until shimmering. Add half of the meatballs and brown on all sides, about 10 minutes, reducing the heat if the oil begins to smoke. Transfer the meatballs to a paper towel-lined plate and repeat with the remaining meatballs. Discard all but 1 tablespoon of the oil left in the skillet.
For the sauce:
  1. Add the onion to the oil left in the skillet and cook over medium heat, scraping up any browned bits, until very soft and lightly browned, 6 to 9 minutes. Stir in the tomato and cook for 1 minute. Stir in the broth, wine, and bay leaves, then carefully return the meatballs to the skillet. Cover and simmer until the meatballs are just cooked through, 5 to 10 minutes.
For the Picada:
  1. While the meatballs cook, prepare the picada by mashing together the parsley, almonds, garlic, saffron, paprika, 1/8 teaspoon salt, and a pinch pepper. When the meatballs are cooked, remove and discard the bay leaves. Stir the picada into the sauce and season with salt and pepper to taste. Transfer the meatballs and sauce to a serving dish and serve immediately.
