How to Make It
Stir together crushed biscotti and butter in a bowl. Press cookie crumb mixture into bottom and 1" up sides of an ungreased 9" springform pan.
Bake at 325° for 10 minutes; let cool.
Meanwhile, beat cream cheese at medium speed with an electric mixer until creamy; gradually add sugar, beating well. Add sour cream and cornstarch, beating just until combined. Add eggs, 1 at a time, beating just until yellow disappears. Stir in lemon rind and remaining ingredients. (Do not overbeat.) Pour batter into baked crust.
Bake at 325° for 50 minutes or until set. Turn off oven. Immediately run a knife around edge of pan, releasing sides. Close oven door, and let cheesecake stand in oven 1 hour.
Remove from oven; cool completely in pan on a wire rack. Cover and chill 8 hours.
