Rosemary Ginger Grapefruit Fizz

Directions

1. In a medium saucepan, heat the fresh rosemary, water and sugar to boiling while stirring and then simmer for 1 minute, turn off the heat and let steep for 30 minutes. Pour into a clean jar through a strainer and store in the refrigerator until use. It will keep in the refrigerator for up to 2 weeks.
2. For each glass, fill a tall glass ¾, full of ice, add 3 oz grapefruit juice, balsamic, 2 tablespoons of the rosemary simple syrup, then fill the rest of the way with club soda or seltzer, and garnish with a grapefruit slice and a rosemary sprig. Can also be enjoyed with gin or vodka or a hard seltzer if you prefer that, just use equal parts of grapefruit juice and alcohol.
