Chocolate Souffles With Peanut Butter Centers - milk

Method

• Bring milk and half and half to simmer in heavy medium saucepan. Whisk egg and egg yolk in medium bowl. Add sugar, cornstarch, and flour to eggs; whisk to blend. Gradually whisk hot milk mixture into egg mixture, then return to same saucepan. Bring to boil over medium-high heat, whisking constantly. Boil 1 minute, whisking constantly. Remove from heat. Whisk peanut butter into hot pastry cream. Strain into medium bowl. Season with salt. Place plastic wrap directly onto surface of pastry cream. Chill until cold, at least 3 hours. DO AHEAD
• Place chocolate and butter in large heat-resistant bowl. Set bowl over saucepan of simmering water; stir until mixture is smooth. Remove from heat; cover. Whisk yolks, 7 tablespoons water, milk, and cocoa in medium bowl until cocoa dissolves. Using electric mixer, beat whites, cream of tartar, and salt in large bowl until frothy. With mixer running, gradually add sugar to egg white mixture; beat until shiny peaks form, about 3 minutes. Add yolk mixture to white mixture; fold (there may be a small amount of liquid that will not blend in). Fold half of egg mixture into warm (not hot) chocolate mixture. Fold in remaining egg mixture. DO AHEAD
• Preheat oven to 350°F. Butter and sugar eight 3/4-cup ramekins or custard cups. Fill halfway with souffl mixture. Spoon rounded tablespoon peanut butter pastry cream into center of each. Spoon remaining souffl mixture atop pastry cream to cover and fill ramekins. Bake until souffles rise about 1 inch above dish and are almost set in center, about 24 minutes. Serve immediately.
