The only thing better than a classic lime margarita, is a key lime margarita! Key limes are tarter than regular limes and have a more aromatic and floral flavor that is just so good in margaritas!
Stir together all ingredients. Taste and add simple syrup if desired.
Pour into a salted-rimmed glass full of crushed ice. Garnish with key lime slices.
Notes
I love my key lime margaritas on the rocks with a salt rim, but you can easily make these frozen instead! Just throw the ingredients in a blender with ice!To make a salt rim, rub a small amount of key lime juice or simple syrup along the edge of your glass. Pour a small amount of margarita salt (or kosher salt) on a plate and gently press the edges of the glass into the salt.
