For the tomato-orange marmalade sauce: Place the olive oil, onion, fennel, garlic, red pepper flakes, and two tablespoons salt in a heavy saucepan over medium-high heat and cook, stirring occasionally, for seven to 10 minutes, or until the vegetables are golden in color and very soft. Add the red wine vinegar and cook for two minutes. Add the tomatoes and pepper. Reduce the heat to medium and cook, stirring occasionally, for 20 to 30 minutes, or until the volume is reduced by a third. Add the orange marmalade and continue to cook for another two to three minutes. Remove from the heat, adjust the salt and pepper to taste, and let cool. Set aside for two to three days if possible. For the meatballs: Preheat the oven to 450 degrees. Combine the egg, cream, wine, panko, parmesan, salt, fennel, cumin, red pepper flakes, paprika, and oregano in a mixing bowl. Allow the panko to absorb the liquid. Add the ground lamb and lamb bacon. Mix evenly until just incorporated. Divide the mixture into about 30 meatballs the size of a ping-pong ball. Place them on a baking sheet with sides and bake for seven to eight minutes. They should only be cooked half way. To assemble: Heat the tomato-orange marmalade and stir in the herbs and butter. Stir in the meatballs and cook over low heat for about five minutes, or until just cooked. Remove meatballs with a slotted spoon to serving dish, leaving whatever marmalade coats them, but not adding marmalade to the dish. Place picks in the meatballs and serve warm.
