Lemon curd is folded into whipped cream and frozen, suffusing the mousse with refreshing citrus flavor. Ingredients 8 to 10 lemons 2 cups sugar 8 large egg yolks 2 whole eggs 1 cup (2 sticks) unsalted butter, cut into pieces 1 ½ cups plus 2 tablespoons heavy cream, chilled Candied Lemon Zest One 8-ounce container creme fraiche Directions Prepare ice-water bath in large bowl. Juice 1 lemon; reserve juice. Juice additional lemons to yield 1 cup. Make lemon curd: Place 1 cup lemon juice, sugar, egg yolks, whole eggs, and butter in saucepan; whisk to combine. Cook over medium heat, whisking constantly until it begins to boil, about 7 minutes. Strain curd through a fine-mesh strainer into a bowl set in the ice bath. Stir periodically until cool; remove from ice bath. Place plastic wrap directly on surface of curd to prevent a skin from forming; refrigerate for at least 1 hour or up to 3 days. Place 1 1/2 cups chilled heavy cream in large mixing bowl; whisk until soft peaks form. Reserve 1/2 cup lemon curd for sauce; add remaining lemon curd to whipped cream. Fold gently until well combined. Place an 8-inch nonstick springform pan on baking sheet. Transfer mousse to springform pan. Place in freezer on sheet until firm, at least 4 hours. Drain candied lemon zest; reserve syrup. Make the lemon sauce: Whisk 1/3 cup syrup, reserved 1/2 cup lemon curd, and reserved juice of 1 lemon in a small bowl. Remove frozen mousse from freezer and let warm 4 to 5 minutes at room temperature. Meanwhile, whisk creme fraiche and remaining 2 tablespoons cream in medium bowl until soft peaks form. Remove sides of springform pan. Slice mousse and place on plates. Spoon lemon sauce around mousse; top with creme fraiche. Garnish with candied zest, and serve. Rate it Print
