Key Lime Pie

The origins of Key Lime pie are a little murky.  Some accounts say that a woman named 'Aunt Sally' invented this lovely combination of cinnamon graham crackers, tart Key Limes, and fluffy meringue. But many historians say that the Bahamian sponge and conch divers were the first to whip it all the local limes with egg and sweetened condensed milk - not whipping cream or milk - but that super thick, canned, sweet goodness. So for all of you out there who absolutely love Key Lime pie, you can whisper a little thank you to my ancestors.  Or you can thank me directly. Either way works for me. 

Oh, and I hate to break it to you, but the majority of Key Lime pies served in restaurants are either 1). artificially colored (Key Lime pie is supposed to be yellow, mainly due to the egg yolks, 2). aren't made with real Key limes, but with your run-of-the-mill Persian limes since real Key limes are hard to come by, 3). all of the above.  Luckily for me, my neighborhood Lowe's Foods had just restocked Key lime, so I was able to make a pure Key Lime pie. Now, I'm not saying that I'm above using a substitute, but it's always great to stay as close to the original recipe as I can.

This is another one of those quintessential summer recipes.  You don't have to keep your oven on for very long, which is always a plus in my books.  It's super light, so you can play cornhole without being weighed down by dessert. You probably have most of the ingredients in your pantry and fridge already.   Plus, it's absolutely delicious.  So go ahead, check your local grocery stores for Key lime and wow your friends and family with this perfect pie.
