Grapefruit/Rosemary Syrup

This is a nice syrup that goes with most base spirits.

Peels from a grapefruit (or two if they’re small)
A few sprigs of fresh rosemary
1 part Water (200ml)
1.5 part Sugar (300ml)

In pot, combine ingredients and bring to a simmer. Keep heat but don’t let it boil for 15-30 minutes. It’ll make the house smell nice. Strain out the solids and cool. Should probably use it a couple weeks after making it.
