   Beat cream cheese, sugar and cardamom in large bowl until smooth. Beat in eggs 1 at a time. Add 1 cup sour cream, pear nectar, flour and vanilla and beat until blended. Pour filling over crust.

3. 3.

   Bake cheesecake until puffed at edges and softly set in center, about 1 hour 5 minutes. Transfer cheesecake to rack; let cool 10 minutes.

4. 4.

   Meanwhile, stir white chocolate in top of double boiler set over barely simmering water until smooth (do not allow bottom of bowl to touch water). Cool chocolate to lukewarm; whisk in remaining 1 1/4 cups sour cream.

   Spread topping over warm filling. Refrigerate cake uncovered overnight. Cut around pan sides; release pan sides. Place cake on platter. Stand brittle pieces on edge in topping on cheesecake.
