1-1/2 cup bread crumbs
1/2 cup butter, melted
3 tablespoons grated Parmesan cheese
3 pkgs. (8 oz each) cream cheese, at room temperature
5 eggs, at room temperature
3 tablespoons onion, grated
1/2 teaspoon lemon extract
1/4 cup butter, melted
4 cups sour cream, at room temperature
7 ounces Black lumpfish caviar, rinsed and drained
For crust: Line bottom of 10-inch springform pan with waxed paper. Mix crumbs, 1/2 cup melted butter and Parmesan in small bowl. Press crumbs firmly against bottom and sides of springform pan. Refrigerate pan while preparing filling.
For filling: Preheat oven to 350 degrees F. Mix cream cheese, eggs, onion, and lemon extract in processor or blender until smooth. Blend in 1/4 cup melted butter. Transfer to bowl. Stir in sour cream. Fold in caviar. Spoon filling into chilled crust. Bake 45 minutes. Turn off oven. Let cheesecake stand in oven 15 to 20 minutes; filling will appear unset.
