If you like a salted rim, rub a lime wedge around the edge of your glass. Dip the rim in salt to coat it evenly.

Using a juicer, extract the juice from fresh limes, oranges, and grapefruits.

In a mixing glass or shaker, combine the tequila, lime juice, orange juice, grapefruit juice, and simple syrup.

Add ice cubes to the shaker and shake vigorously for about 15 seconds.

Fill your prepared glass with ice and strain the mixture over the ice.

Pour club soda over the mixture to add fizz.

Add a slice of lime or orange on the rim for garnish.

Stir gently to combine, then serve immediately.
