Rosemary is a great match for the botanicals of No. 3 London Dry Gin and the Peychaud's helps to ramp up the anise flavors brightened with a bit of lemon juice. Simple, herbaceous and refreshing.

.5 oz Rosemary Simple Syrup (1:1)
.75 oz Fresh Lemon Juice
2 dashes Peychaud's Bitter
Add all ingredients to cocktail shaker filled with ice. Shake vigorously for 15-30 seconds. Strain into chilled cocktail glass. Garnish with rosemary and lemon zest.
