I tried this out for the first time. I'm so hooked on all things key lime after traveling through the Keys. It was such a fun time, and I had to learn how to make this pie!
I'd say it worked out amazingly. It was my first go, and wow, was it easy!
I found a good receipt, and adapted it as follows:
1 1/4 cups graham cracker crumbs
2 tablespoons sugar
5 tablespoons butter, melted
1 (14 ounce) can Sweetened Condensed Milk
2/3 cup fresh lime juice
1/2 cup sour cream
2 teaspoons grated lime peel
1 cup heavy whipping cream
1/4 cup powdered sugar
1/2 teaspoon vanilla extract
Heat oven to 325 degrees F. Combine graham cracker crumbs and sugar. Add melted butter and stir until evenly moistened. Press mixture into bottom and sides of a 9-inch pie plate to form crust. Bake 10 minutes or until crust begins to brown. Cool 15 minutes on wire rack.
Whisk sweetened condensed milk, lime juice and sour cream in large bowl until blended. Stir in lime peel. Pour filling into crust. Bake 10-18 minutes or until tiny bubbles begin to form on surface of pie. Cool completely on wire rack.
Beat cream, powdered sugar and vanilla in large mixing bowl with electric mixer on medium speed until stiff. Top pie with whipped cream. Chill at least 1 hour before serving. Best served the same day.
(I've tried freezing mine so I'll keep you posted if it worked well!)
