1/4 oz Patron Citronage Orange Liqueur
1/4 oz Yellow Chartreuse
3/4 oz Lemon Juice
1 oz Ginger Syrup (*)
1/2 oz Demerara Syrup (*)
The whole mix was diluted by ice melt to chill (with additional water added to a total of 2-3 oz water) and then carbonated for draft dispense. It was dispensed into a Highball glass with ice cubes (some with flowers frozen inside) and a straw.
(*) Perhaps shaking the first 4 ingredients with ice and straining into a Collins glass with 3 oz of ginger beer would work similarly. Here, the ginger beer would be substituting for the ginger syrup, demerara syrup, some of the water, and the carbonation.
