Add the tequila, lime juice, triple sec, and agave syrup into an empty gallon jug. Place the lid on the jug and shake until well combined.
Gently fold your fruit slices in half and place them into the jug.
Notes
Storage:
To Store: If you have leftovers, you can store the margarita mixture in the fridge for a few hours to a day.
Tips:
To keep your margarita cool and refreshing, pour it over ice. You can also chill your cocktail glasses in the fridge or freezer for about 15 minutes before serving.
You can rim your glasses by running a lime wedge around the edges and dipping them in a coarse sea salt or kosher salt.
Feel free to serve your margaritas over crushed ice for a frozen version.
