I fell in love with this drink when I was on holiday in Japan and spent a few relaxing days in Okinawa. The hotel had a not-too-shabby cocktail bar, and this was one of the house specials.
The Sidecar balances three strongly-flavoured ingredients - the kick of the brandy is tempered by the Cointreau, and lemon juice provides a powerful citrus overtone.
Not one for the faint-hearted.
