Key Lime Pie

Can you see how delicate and creamy that custard is?! This is the best Authentic key lime pie.

Key lime pie. I make about 17 billion of these every year. Not exaggerating. But it’s the boys (and Pat’s) favorite pie to eat. It reminds me of Florida, my favorite place to live while growing up. And I’ve become a great proficient at making it. All win win wins. So I keep making it. But If I’m really honest, it does not take 17 billion times of practice to become a great proficient at making this pie. If you’ve been around here for a while, you know how I feel about labeling recipes “easy” but this one really is. There’s no way around it. Mix cracker crumbs, melted butter, and sugar in a pie pan. Press to make a crust. Whisk condensed milk, egg yolks and lime juice in a bowl. Pour it over the crust. Bake. Decorate. Done.

The only way to mess this pie up is to over bake it. Be sure to set a 15-minute timer and you’re golden. I use bottled key lime juice instead of juicing a thousand tiny limes. If you choose to do the same, make sure that you get key lime juice. Not lime juice from the Florida Keys or some other sad way of labeling regular lime juice. If you can’t find key lime juice that’s fine. It will still taste lovely but don’t call it Key Lime Pie. You’ll upset the entire state of Florida and they’re all crazy enough. I should know. I’m from there.
