Prepare your margarita glass by rubbing a lime wedge along the rim.
Dip the rim into salt to coat it evenly.
Fill a cocktail shaker halfway with ice cubes.
Add the silver tequila, triple sec, and key lime juice.
Include the simple syrup into the shaker.
Make sure all ingredients are in before sealing it tightly.
Shake the mixture vigorously for about 30 seconds.
This helps to combine flavors and chill the drink thoroughly.
Strain the margarita into your prepared glass over fresh ice cubes.
