Escargot Tray (Snails in Garlic Butter)

Frozen Escargots de Bourgogne are a classic French delicacy, typically large snails (Helix pomatia) stuffed in their shells with a rich parsley and garlic butter, sold in oven-ready trays, and cooked directly from frozen for about 10-15 minutes at 180c until sizzling, served hot with crusty bread for soaking up the buttery sauce.
