Does anyone just love the combination of sour and sweet? Lemon, lime, and orange in a dessert really give it a brightness that I love.  If you like a little sweet and a little sour, you are sure to love these key lime pie bars! And who knew how easy it is to make these delicious bars? A simple graham cracker crust filled with a super simple filling that’s just a handful of ingredients. Add some whipped cream on top if you desire and the rest is history.

What is the difference between limes and key limes?

There are not a lot of differences, but there are a couple of differences. Regular limes are much bigger than key limes, but that’s obvious, right? While regular limes are bright green in color, key limes are more of a yellow color when they are ripe. While they are very similar in flavor, key limes are a bit more acidic and have more of a floral note to them. The tangy taste of the key limes makes them great for cooking as their bold flavor holds up well to being cooked.

Can I substitute regular limes in key lime pie bars?

If you want to make a key lime pie but are unable to find them, you can use regular limes. As long as you are using fresh limes, key limes, or regular limes it will turn out fine. It will change the overall flavor a bit. As mentioned above key limes are tangy without a harsh flavor and have more of a floral note to them. So you can definitely sub, but it won’t taste exactly like a TRUE key lime pie. So whatever you do, don’t try to pull a big one on Uncle Bob.

Where do I find key limes?
