About Key Limes:

Key limes are typically sweeter in taste than regular Persian limes, making them a perfect ingredient for the refreshing pie they’re most known for. They’re tiny limes, and they’re often yellow in color. You can substitute regular limes in this margarita key lime pie if you have trouble locating key limes.

    It was good! Making it, I wasn’t so sure . . . I did add lime zest to custard part because it just wasn’t tasting “limey”! Also, I added the alcohol after the cooking because I wanted more of the boozy taste. The volume of all ingredients was WAY more than a 9 inch pie plate – easily could have been a 10 inch or deep dish. We topped it with whipped cream and a sprinkle of lime zest for presentation. My husband and guests LOVED it! This is a great make ahead desert! Thanks so much!

    What can I substitute for the liquor. I don’t use alcohol. I want my grandchildren to eat it. Looks so delicious.
