Pour into oiled 9-inch pie plate and press mixture evenly on bottom and up sides to form crust. Bake 5 minutes; let cool while preparing filling.

Filling: Blend all ingredients in food processor or blender until very smooth, about 30 seconds.

Pour into crust. Bake until top of pie is slightly browned, about 30 minutes. Cool and refrigerate until thoroughly chilled and firm, about 2 hours. Makes 8 servings.

*Alternatively, use a prepared graham cracker crust.

*For a no-bake cheesecake, omit cornstarch mixture. Pour filling into crust and refrigerate until firm, at least 2 hours or overnight. The texture will resemble that of a cream pie.

*Add vanilla-flavored liqueur instead of lemon juice and zest for a vanilla cheesecake.

*Reduce the sweetener, eliminated the lemon juice and zest, and add pureed raspberries *If the fat content doesn't concern you too much, add 12 ounces of melted semisweet chocolate instead of fruit.

*To serve as a pudding, omit the crust and pour the filling into custard cups.
