3/4 C. cookie or graham cracker crumbs
2 T. granulated sugar
3 T. melted butter
16 oz. cream cheese (regular or lite)
2/3 C. granulated sugar
1 egg yolk
1/4 C. frozen orange juice concentrate, thawed
1 tsp. orange or lemon zest or dried grated rind
1 T. all-purpose flour
1/2 tsp. vanilla extract
Combine crumbs with sugar; mix in melted butter until well moistened.
Pat into a 7-inch springform pan.
In a medium bowl, cream together the cream cheese and sugar. Add eggs and yolk and beat for about 3 minutes on medium with a hand-held electric mixer. Beat in orange juice, zest, flour, and vanilla. Beat for another 2 minutes.
Pour batter into prepared crust; place on a rack or aluminum foil ring in a crock pot (so it doesn't rest on the bottom of the pot). Cover and cook on HIGH for 2 1/2 to 3 hours.
Turn off and leave for 1 to 2 hours, until cool enough to remove.
