- You can do this in a cocktail mixer if you want, but I do it right in the glass. Put the mint leaves in the bottom of a tall glass along with the sugar and smash them a bit with the back of a spoon. If you have a muddler, use it.
Add the grapefruit juice, fresh lime, rum, Rose's, and blood orange juice or soda if using, along with the ice. Stir gently. Fill the rest of the glass with sparkling water. Garnish with a lime wedge and more mint leaves. Be sure to taste your drink and adjust it to suit you!
