Prepare the Glass: Begin by rimming your glass with coarse salt or sugar. To do this, run a lime wedge around the edge of the glass and then dip it in salt or sugar, creating a nice even coating.

Fill the Shaker: Fill a cocktail shaker about halfway with ice cubes. This will help chill the ingredients nicely.

Add the Ingredients: Pour in the tequila, blue curaçao, lime juice, and simple syrup into the shaker. You can adjust the quantities slightly based on your preference for sweetness or strength.

Shake It Up: Secure the lid on your shaker and give it a good shake for about 15-20 seconds, or until everything is well-combined and chilled.

Strain and Serve: Strain the mixture into your prepared glass filled with ice. If you prefer a more polished presentation, use larger ice cubes which melt slower, keeping your drink well-chilled without diluting the flavors.

Garnish and Enjoy: Finally, garnish your Blue Margarita with a lime wheel or wedge. Sip, savor, and let the tropical vibes wash over you!
