The pie is fabulous. It's tart, sweet, and oh, so cool. I used regular limes. Have you seen how tiny key limes are? You can't juice them with a juicer. The truth is limes were on sale for .79 cents (for a whole bag)! You can't beat that price!
The pie is a perfect summer dessert. It has an ice cream texture to it, very smooth and rich. The only problem I had with the recipe was that it called for 6 raw egg yolks. I decided to "cook" my eggs via the "double boiler" method & by adding 2 teaspoons of Knox gelatin.
I cooked the eggs, sugar, and lime juice over a double boiler, until they reached a 140 degrees (I reserved 2 tablespoons of lime juice to dissolve the gelatin in). Then I slowly added the condensed milk and the gelatin. Next, fold in the lime zest. Pour the mixture into the pie crust and freeze over night. Decorate with fresh whipped cream.
