Gather Your Ingredients: Make sure you have all the required ingredients laid out on your countertop. Fresh juices are key to a flavorful cocktail.

Prepare the Shaker: Fill a cocktail shaker halfway with ice cubes to ensure the drink chills properly.

Add the Ingredients: Pour the tequila, Campari, lime juice, grapefruit juice, and simple syrup into the shaker.

Shake Well: Secure the shaker lid and give it a vigorous shake for about 15-20 seconds. This will mix all the ingredients and chill them to perfection.

Strain and Serve: Use a strainer to pour the mixture into a chilled cocktail glass. Ensure there are no ice shards in the drink.

Garnish: Add a twist of grapefruit peel as a garnish on the edge of the glass for an elegant touch.
