Step 1

Preheat oven to 350°F if using a silver 9-inch springform pan (or to 325°F if using a dark nonstick springform pan). Mix graham crumbs and melted butter until well blended; press firmly onto bottom of pan. Beat cream cheese and 3/4 cup of the sugar in large bowl with electric mixer on medium speed until well blended. Add 3 of the eggs, one at a time, mixing on low speed after each addition just until blended. Stir in 1 Tbsp. of the lemon peel. Pour over crust.

Step 2

Bake 45 to 50 min. or until center is almost set. Run knife around rim of pan to loosen cake; cool before removing rim. Refrigerate at least 4 hours before serving.

Step 3

Meanwhile, beat remaining 3 eggs and remaining 3/4 cup sugar with wire whisk until well blended. Add remaining 1 Tbsp. lemon peel, the lemon juice and 2 Tbsp. butter; mix well. Microwave on HIGH 2 min.; beat until butter is completely melted and mixture is well blended. Microwave an additional 2 min. or until mixture just comes to boil and is slightly thickened; stir. Cool completely. Cover and refrigerate until ready to use. Drizzle sauce evenly over cheesecake slices before serving.
