Key Lime Pie Ice Cream

For some reason I've been making a lot of homemade ice cream lately.  This recipe is delicious and so simple.

1 1/2 cups milk
1/2 cup Key Lime juice (you can use fresh key limes, or I just used Nellie and Joe's Key Lime Juice in a bottle)
1/2 cup heavy cream
1 can sweetened condensed milk
1 prepared graham cracker crust

Combine first four ingredients.  Pour into freezer can of an ice-cream freezer and freeze according to manufacture's instructions.  When done stir in graham cracker crumbs from pie crust, reserving some crumbs to garnish.  Put ice cream into a freezer-safe container, cover and freeze for 1-2 hours or until firm.  Serve sprinkling each serving with graham crackers (also can garnish with lime wedge).
