Simple Syrup is equal parts sugar to hot water. It keeps a level of consistency in sweetness from drink to drink. Simply mix equal parts of sugar and hot water, and allow to cool before use. For this recipe, I recommend pouring the hot water over rosemary (dried or fresh) and letting it steep like a tea for 5 minutes before mixing in the sugar. This allows for a fun and easy way to add nuanced and unique flavors to your concoctions.
