How to Make It
Place an oven rack in lower third of oven, and preheat oven to 400°. Drain oysters, reserving 1 1/2 cups oyster liquor. Cook bacon in a Dutch oven over medium heat, stirring occasionally, 8 minutes or until crisp. Drain bacon on paper towels; reserve 3 Tbsp. drippings in Dutch oven.
Add butter and next 4 ingredients to Dutch oven; sauté 5 minutes. Add garlic and lemon juice; cook 1 minute. Add wine, and cook 2 minutes. Sprinkle with flour; cook, stirring constantly, 1 minute. Stir in cream, next 4 ingredients, and reserved oyster liquor; bring to a boil. Boil, whisking constantly, 2 minutes.
Remove from heat; stir in oysters and bacon. Spoon mixture into 6 lightly greased 12-oz. ramekins. Cut pastry sheets into circles slightly larger than ramekins, and place 1 on top of filling in each ramekin. Whisk together egg and 1 Tbsp. water; brush mixture over pastry.
Bake at 400° on lower oven rack 30 to 35 minutes or until browned and bubbly. Let stand 15 minutes before serving.
