Goat Cheesecake

Heat oven to 350 degrees. Mix graham cracker crumbs with butter in a small bowl until thoroughly blended; press crumbs firmly on bottom of a greased 9-inch springform pan with your fingers. Beat cream cheese in a large bowl with an electric mixer until thick, smooth and creamy, about 5 minutes. Beat in 1 cup of the sour cream, the goat cheese, eggs and sugar, and continue beating until mixture is very smooth and creamy, 4 to 5 minutes. Beat in vanilla and lime juice until thoroughly incorporated, 2 minutes more. Pour filling over crust and smooth top. Bake until filling is brown and springy-firm, about 1 1/2 hours. Remove from oven and allow to cool to room temperature. Refrigerate at least 6 hours or overnight. Combine Grand Marnier with the remaining 1/2 cup sour cream in a small bowl and beat with an electric mixer on medium speed until smooth and creamy, about 2 minutes. Spread on top of cooled cake. Remove cheesecake from refrigerator about 2 hours before serving. To serve, cut cake in wedges with a warm knife. Yield : 12 to 14 servings
