This striking, very floral, pale aquamarine-yellow riff on the Corpse Reviver No.2 (with crème de violette replacing Lillet Blanc) is not so far removed...
After reading the comments we decided to cut back on the sugar syrup and up the gin by 1/4 oz. Very pleasant, but still a bit sweet. Would try again but with 1 1/4 oz gin and no sugar syrup. Very good, just a bit sweet.
The original equal parts recipe - 25mls each of creme de violette, gin, triple sec & lemon juice - plus 10mls sugar syrup & 4 or 5 drops of orange cream citrate is also delicious
