BITTERSWEET CHOCOLATE SOUFFLES

Steps:

• Preheat oven to 400 degrees, with the rack in lower third. Place six 10-ounce ramekins on a rimmed baking sheet. Brush inside ramekins with butter. Dust with sugar, and tap out excess. Using kitchen twine, secure a strip of parchment paper around each ramekin so that parchment extends 3 inches above rim. Chill in freezer 15 minutes (up to overnight).
• Bring milk almost to a simmer in a medium saucepan over medium heat. Remove from heat; set aside.
• Put 1/2 cup sugar and the egg yolks into the bowl of an electric mixer fitted with the whisk attachment. Beat on high speed until pale, 3 to 4 minutes. Reduce speed to low; beat in flour. Add about one-third of the hot milk in a slow, steady stream, beating until just combined.
• Pour yolk mixture back into pan with the remaining milk. Bring mixture to a simmer over medium heat, and cook, stirring constantly, until thick, about 2 minutes. Transfer to a large bowl. Stir in chocolate, vanilla, and 1/8 teaspoon salt. The souffle base can be made a day ahead and refrigerated, covered, until ready to bake the souffles.
• Put egg whites and a pinch of salt into a large copper bowl. Using a balloon whisk, beat until foamy. (Alternatively, beat egg whites and a pinch of cream of tartar instead of the salt in the bowl of the electric mixer fitted with the whisk attachment.) Add 1 tablespoon sugar, and beat until soft peaks form. Add remaining tablespoon sugar, and beat until stiff peaks form.
• Using a rubber spatula, fold one-third of the egg whites into chocolate mixture. Gradually fold in remaining egg whites.
• Carefully pour batter into prepared ramekins on baking sheet, filling to just below rims. Bake 10 minutes. Reduce heat to 375 degrees; bake until set, about 15 minutes. Remove parchment. Poke a hole in top of each, and pour in caramel creme anglaise. Serve immediately.
