How to make:
SHAKE all ingredients with ice and fine strain into chilled glass.
Lemon zest twist (some like with a sugared rim)
Complex and balanced but still a 'sour'. Those with a sweet tooth may prefer with a sugar rim. Also consider trying what has become something of a standard modern recipe:
1 2/3oz / 50ml) Cognac
1oz / 30ml Triple sec
2/3oz 20ml Lemon juice
