There's one rule to keep in mind when you are looking for Florida's signature dessert, Key Lime Pie. If it's green, it's not a real Key lime pie. You'll find the best Key lime pies are slightly yellowish in color but mostly a creamy color and consistency. Key lime trees are abundant in south Florida but sometimes you can get them in your own area grocery store. Here's an easy recipe to try:
1 9" prepared graham cracker pie crust (or make your own)
1 can sweetened condensed milk
4 large egg yolks
1/2 cup plus 2 Tbls fresh or bottle Key lime juice
heavy cream for whipped topping
Preheat oven to 350°
Whisk together egg yolks and condensed milk until well blended. Add Key lime juice and whisk again until blended well. Mixture should thicken a bit.
Pour into prepared crust. Bake in the middle of the oven for 15 minutes. Cool completely on rack and then chill for 6-8 hours.
Just before serving, whip cream and spread on top of pie. Garnish with a couple of thin lime slices if available.
