Property of a lady
Recover from a traumatic auction experience with:
1 measure gin
6 basil leaves
1/4 measure green Chartreuse
1/4 measure lemon juice
A dash of sugar syrup
Shake with ice for a minute. Double strain (or else you'll end up with basil bits).
Reshake cocktail with egg white - vigorously.
Strain, pour and float a basil leaf on top.
[Cocktail aficionados may recognise this as a Green Park with added green Chartreuse and modified measures]
