Key Lime Pie has always been one of my favorite summer desserts. I think the rich and luxurious texture has the perfect combination of tangy and sweet. A fun fact about this pie is that traditional recipes always call for sweetened 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.
My parents made a trip to visit Ann Arbor last weekend and I made this pie for dessert. This was no coincidence because it also happens to be one of my dad’s favorite desserts as well! He gave it two thumbs up, which is high praise coming from a food lover like him.
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.

In a medium bowl, combine condensed milk, sour cream, lime juice, and lime rind. Mix well and pour into graham cracker crust.
Bake in preheated oven for 10-12 minutes, until set and tiny pinhole bubbles burst on the surface of pie. Be careful not to brown your pie. Remove from oven and chill pie thoroughly before serving. Garnish with lime slices and whipped cream if desired.
