Blue margarita is one of the popular summer drink that made with tequila and blue curacao. Although it is a summer drink but you can enjoy the drink any season of the year.
Spread some kosher salt on a plate or flat place. Take a margarita glass, wet its rim with a lime wedge. Now take the glass and dip the rim of the glass on the kosher salt.
Fill the cocktail shaker with tequila, blue curacao, lime juice, agave syrup, and ice cube. Shake the cocktail shaker vigorously until it cools down.
Fill the prepared glass with the cocktail. Enjoy the drink.
Notes
Agave Syrup is an optional ingredient for this drink. You could skip this. But I suggest adding this ingredient for more variations.
