for the rosemary grapefruit simple syrup (makes about 1-1/2 cups):
1 cup water
3/4 cup organic cane sugar
1/4 cup honey
1/4 cup fresh grapefruit juice
2 large strips of grapefruit zest
2–3 large sprigs of fresh rosemary
for the honey rosemary grapefruit sodas:
1–2 parts rosemary simple syrup
2 parts fresh grapefruit juice
3–4 parts sparkling water (I like LaCroix)
ice/fresh rosemary sprigs/grapefruit slices for serving/garnish
make the rosemary grapefruit simple syrup:
Heat the water, sugar, honey, and grapefruit juice in a medium sauce pan over medium heat, stirring occasionally, until the sugar is dissolved, about 5 minutes.
Add the grapefruit zest and rosemary, and let gently simmer for another 5 minutes. Remove from the heat, and steep for up to an hour.
Strain through a fine-mesh sieve into a glass jar, and chill before serving. Can be made in advance, and stored in the refrigerator for about a week.
make the honey rosemary grapefruit sodas:
To serve, fill a highball glass with ice. Add the rosemary simple syrup and fresh grapefruit juice. Stir to combine. Top with soda/sparkling water.
Garnish with grapefruit slices and/or a sprig of rosemary. Serve and enjoy!
Make it boozy: Add 1 shot of gin before topping with soda.
Make it a rosemary paloma cocktail: Add 1 shot of tequila and a big squeeze of lime to the rosemary simple and grapefruit juice. Cheers!
Make it vegan: Swap pure maple syrup or organic cane sugar for the honey.
Make it paleo: Swap out the cane sugar, and use a full cup of honey. The honey flavor will be more pronounced, but equally delicious!
