Season the mushroom caps with salt, pour the oil over them and sweat them in the oven. Take the mushroom caps out and place 4-5 snails in each one. Cover with snail butter and heat in the oven just before serving, exactly as you would snails in their shells. Dry white wines: Quincy, Pouilly-Fume, Bourgogne-Aligote. Red wines: Saint-Emilion, Chinon, Bourgueil, Rully, Beaujolais-Villages. [From "Larousse Traditional French Cooking."]
