Key Lime Ice Cream Pie

1. 1

   Combine 1 cup sugar and next 3 ingredients in a large saucepan. Scrape seeds from vanilla bean; add seeds and bean to milk mixture. Bring to a boil over high heat. Immediately remove from heat, and let stand 30 minutes. Remove and discard vanilla bean.

2. 2

   Combine graham cracker crumbs and next 4 ingredients in a medium bowl, tossing until well blended. Press crumbs into a 9-inch glass or ceramic pie plate to form an even crust. Bake at 350u00b0 for 8 minutes or until firm to the touch; cool completely, and set aside.

3. 3

   Beat egg yolks in a large bowl. Slowly whisk 1 cup warm cream mixture into egg yolks. Add egg mixture to remaining cream mixture, whisking constantly.

4. 4

   Cook cream mixture over medium heat, whisking constantly, 5 minutes or until mixture reaches 160u00b0 and coats the back of a spoon. Remove from heat; pour through a fine wire-mesh strainer into a bowl. Cool custard completely, stirring occasionally.

5. 5

   Combine remaining 2/3 cup sugar and Key lime zest and juice in a bowl, stirring until sugar dissolves. Stir lime juice mixture into cooled custard. Transfer custard to an ice cream maker, and process according to manufacturer's directions.

6. 6

   Mound ice cream into prepared crust. Freeze pie 4 hours or overnight. Garnish, if desired.
