2 1"-thick slices white country bread (about 5 oz.),
cut into chunks
1 1⁄4 cups milk
9 strips smoked bacon (6 oz.), cut into 1⁄2" pieces
1⁄2 onion, roughly chopped
1 1⁄2 tsp. kosher salt
3⁄4 tsp. freshly ground black pepper
6 oz. pancetta, cut into 1⁄2" x 1⁄4" pieces
4 oz. ground pork shoulder or belly
1⁄4 cup chopped flat-leaf parsley leaves
2 tbsp. chopped chives
1 cup flour
40 pitted prunes (about 12 oz.)
1. Heat oven to 400°. Combine bread and milk in a bowl; set aside to let soak for 10 minutes. Grease an 8" x 8" baking pan; set aside.
2. Meanwhile, cook bacon in a 10" skillet over medium heat, stirring frequently, until it has rendered its fat, about 8 minutes. Add onions, salt, and pepper and cook until softened, about 15 minutes.
3. In a food processor, process bread–milk mixture, bacon–onion mixture, pancetta, pork, parsley, chives, and egg to a fine paste. Add flour; pulse until combined. Scrape into a bowl; fold in prunes.
4. Transfer mixture to the prepared pan, smooth top with rubber spatula, and cover with foil. Bake for 30 minutes. Remove foil; continue to bake until lightly browned and a knife inserted into center comes out clean, about 45 minutes. Let pan cool on a rack for 15 minutes. Cut into 1"-thick slices and serve.
