Rub the rim of the glass with the 1/4 piece of orange, pour some Salty Chilli Cocktail Rim onto a small plate, then roll the moistened rim of the glass onto the salt. Add 5 ice cubes and set aside.
Then place 5 ice cubes in the cocktail shaker. Pour the tequila, Cointreau, orange blossom water, agave syrup and lime juice. Shake vigorously and pour the margarita mix into the glass.
Decorate with a piece of orange peel. Enjoy!
