For each portion you will need the following
3 tbsp of sugar
2 tsp of rosemary
2 tsp of lemon zest
juice from one lemon
liquor of your choice (gin and vodka work best)
Put the sugar, rosemary and lemon zest into your mortar and pestle (or food processor) and blend them until the rosemary and lemon is incorporated. Rim your glass with this sugar mixture and then add the juice from your lemon. blend this together until the sugar has disolved. This should give you about 5tbsp of liquid per drink. Add this to the glass, add the amount of liquor you would like and top the whole thing off with ice and soda water.
Perfect for a hot summer day.
