Place two tablespoons of salt onto a small plate. Run lime wedge around rim of a cocktail glass and dip edge of glass into salt and rotate the glass on its side to evenly coat the outside of glass rim. Fill glass with ice and set aside.

In a cocktail shaker, add enough ice to fill halfway. Add tequila, orange liqueur, mango puree, lime juice, and agave syrup. Top cocktail shaker and shake until well chilled.

Strain into prepared glass and garnish with a mango or lime wedge, top off with soda or sparkling water and enjoy!
