This was the first thing I made for my wife, back in January of 2008. I told her I'd make her a cheesecake, and gave her the opportunity to chose what kind, but she took too long. And since Santa couldn't find any white chocolate Terry's Oranges this year, this is the recipe I used (from the Nestle website)
1 1/2 cups chocolate graham cracker crumbs
1/3 cup butter, melted
1/2 cup orange juice
1 envelope unflavored gelatin
2 cups (12-oz. pkg.) NESTLÉ® TOLL HOUSE® Premier White Morsels
2 pkgs. (8 oz. each) cream cheese, softened
1/3 cup granulated sugar
1 cup heavy whipping cream
2 tablespoons finely grated orange peel
Fresh orange slices and chocolate graham cracker crumbs (optional)
Preheat oven to 350° F.
Combine crumbs and butter in medium bowl. Press crumb mixture onto bottom of ungreased 9-inch springform pan. Bake for 10 minutes; cool in pan on a wire rack.
Combine orange juice and gelatin in small saucepan. Heat over medium heat, stirring occasionally, until gelatin dissolves.
Chop chocolate into small chunks (so it will milt easier), and microwave uncovered, microwave-safe bowl on medium-high (70%) power for 1 minute; stir. The morsels may retain some of their original shape. If necessary, microwave at additional 10- to 15-second intervals, stirring just until melted.
Beat cream cheese and sugar in large mixer bowl until combined. Gradually stir in gelatin mixture and melted morsels.
Beat whipping cream in small bowl until soft peaks form. Gently fold whipped cream and orange peel into cheese mixture. Pour filling over crust. Cover; refrigerate for 6 to 24 hours or until firm. Garnish with orange slices and chocolate graham cracker crumbs, if desired. Remove side of pan.
I've made this with chocolate crumbs, and with graham crumbs. Both are good, but the graham crumbs seemed to go over better. I've also topped with chocolate ganache (which went over better with me.

).
Instead of a 9" springform pan, I've also used mini cupcake tins (24 per sheet). They popped right out of the non-stick pan, with no issues. It made 48 mini's, and 6 larger ones. The mini's were great for a party we attended, which was the point.
