This is an awesome recipe I got from June's Princess Captain's Circle Newsletter:
Many Princess cruises depart from sunny Florida, and our traditional Key Lime Pie brings the sunshine directly to your table. Simple to prepare, beautiful to serve and wonderfully light and delicious, Princess chefs take great pride in serving this fresh pie to passengers and we know you’ll delight in sharing it with friends at home.
Traditional Florida Key Lime Pie
1 ½ cups graham cracker crumbs
2 tbsp sugar
4 tbsp melted butter
14 oz. sweetened condensed milk
3 egg yolks
½ cup key lime juice
2 tsp lime zest
For Crust: Preheat oven to 350°. In a medium bowl, mix graham cracker crumbs and sugar. Add melted butter and mix well. Press graham cracker crumb mixture evenly over bottom and sides of a 9" pie pan. Bake for about 10 minutes until crust just starts to darken slightly. Remove from oven and set aside.
For Filling: Pour sweetened condensed milk in a mixing bowl. Add egg yolks one at a time, mixing after each addition. Slowly add the key lime juice while mixing. Pour mixture into baked pie crust. Bake for about 15 minutes until filling is set in the center.
To serve, spread top of pie with whipped cream and sprinkle with lime zest.
If green color is desired, add 1-2 drops of green food coloring to filling before baking.
