Pour tequila into a martini shaker with lots of ice. Squeeze 1 full lime, 1 half lemon, and 1 slice of an orange. Splash POMJuice, splash Cointreau, and splash Margarita mix (only a SPLASH!!).
Garnish a glass with pink sugar. Shake for about 30 seconds and pour over ice.
Add soda water to the top (do this AFTER you shake everything up)
Garnish with an orange slice!
