1/2 oz Saint Germain elderflower liqueur
1 shot (1 1/2 oz) Pimm's No. 1
1 shot white rum
fill with about 2 parts Dry Soda cucumber soda to 3 parts Reed's ginger brew
1-2 dash(es) orange bitters
garnish with a cherry
A spur-of-the-moment concoction that turned out pretty well in one try, with just the addition of the orange bitters. OF course, Pimm's, ginger ale, and cucumber are known to be a good match, and rum goes with everything, but the two flower liqueurs were grasping at straws. This is the first drink I've concocted with Dry Soda cucumber soda that didn't just taste like cucumber soda. 1/2 oz of creme de violette is usually too much, but here its presence is fairly subtle (while still noticeable).
The "2 to 3" proportion of the sodas is an estimate. I just poured from both bottles at the same time at about the same rate, and stopped pouring cucumber soda about a half an inch from the top of the glass. The sides of the glass are diagonal, so who knows what the exact proportions were. I'm pretty sure it's altogether about 1-to-1 between boozes and mixers.
I have no idea what to call this.
