Instructions

Make simple syrup: Combine water and sugar in medium sized saucepan and bring to a boil. Cook just until sugar dissolves. Remove from heat and steep rosemary sprigs in syrup 30 minutes.  Remove rosemary, pour into clean container with lid and refrigerate. Simple syrup will keep in fridge for a month. Use to sweeten tea, lemonade or other cocktails!

Make drinks/garnishes: Slice grapefruit and several limes into thick slices, then cut slices into four or six wedges each. For lime peel (optional), peel off long strips of lime, remove white pith from back and cut into thin strips.  Set out bucket of ice and self serve tray with spoons. On tray place: simple syrup, rosemary sprigs, half of grapefruit and lime slices + peels. In tall pitcher, combine grapefruit juice, lime juice and tequila. Add in remaining citrus slices + peel; stir well. Cover and chill until ready to serve.

Rim glasses: Squeeze the juice of two limes onto one paper plate and sprinkle kosher or sea salt onto another plate. Turn glass upside down to coat with lime juice and then place wet rim in salt and twist glass to coat. Tap off excess.

Serve: Fill rimmed, salted glasses with ice and margarita mix. Garnish with a rosemary sprig. Let guests add in their own syrup and extra citrus.
