In a skillet, cover the pancetta with water and bring to a boil. Simmer for 2 minutes; drain and wipe out the pan. Cut the pancetta into 1/2-inch pieces and return to the skillet. Cook over moderately low heat, stirring, until the pancetta is browned, 15 minutes. Add the ham and cook for 1 minute. Using a slotted spoon, transfer the meat to a plate. Stir in the paprika, cumin and anise seeds.
