Why you'll love this recipe
So let’s talk about this pie a little bit. This Key Lime Pie recipe uses condensed milk and sour cream. It is a fabulously easy way to whip up a summertime favorite dessert in under an hour. You can even use bottled key lime juice to save some additional time. Don’t forget to garnish with whipped cream as this helps cut the tartness of the lime.
Why we use condensed milk
No fresh milk, no refrigeration, and no ice was available in the Keys until the arrival of tank trucks with the opening of the Overseas Highway in 1930. Because of this lack of milk, local cooks had to rely on canned sweetened condensed milk. Key lime may be the star ingredient of the key lime pie, but it is the sweetened condensed milk that makes it so smooth and delicious.
