Braised Lamb with Garlic, Wine, and Lovage

Roughly grind coriander seeds, peppercorns, and cloves with a mortar and pestle; set aside. Heat 3 tablespoons oil in a Dutch oven over medium-high. Add lamb pieces in a single layer, working in batches if needed, and cook, turning occasionally, until well browned on all sides, about 8 minutes. Add onion, salt, and coriander mixture. Cook, stirring occasionally, until spices are fragrant, about 2 minutes. Add wine, 1 tablespoon lovage, sage leaves, bay leaves, and garlic. Cook, stirring occasionally, until liquid is slightly reduced, about 2 minutes. Stir in passata, and bring to a boil. Reduce heat to medium-low, cover, and simmer until lamb is tender, about 2 hours.

Preheat broiler to high with rack in middle of oven. Uncover lamb, and cook over medium-low until sauce is thickened, about 20 minutes, skimming off fat as needed. Brush 1 side of bread slices evenly with remaining 2 tablespoons oil, and place on a baking sheet. Broil in preheated oven until lightly toasted, about 6 minutes. Serve braised lamb and sauce over bread; sprinkle with remaining 3 tablespoons lovage.
