For Rimming Glass: Pour some kosher salt onto a plate, and then add some zest of the grapefruit and lime. Use your fingers to mix it together. Then slice your grapefruit in half and slice a little wedge off of one half for garnish. Rub a little of the wedge along half or the whole rim of the glass, and then dip the glass into the salt mixture.

 

For Cocktail: Add the juice of half a grapefruit and half a lime to your cocktail glass. Then sweeten it up with 1 teaspoon of agave syrup, and stir. Now add 1/4 cup of tequila and stir. Finally add 4-5 ice cubes and top off with sparkling water and enjoy!
