I was recently at a fancy restaurant and had a fabulous cocktail. I checked the menu online and it has gin, tonic, soda, cucumber...and..:"rosemary lemon syrup." Any idea of how I might make this syrup. I'm trying to replicate it for a wee party I'm having next Friday night for the Royal Wedding. Served in china teacups, of course. I will be resplendent in a big hat that looks like meringue. Any help will greatly help my cheesy fun.
