I was looking for something gin-forward the other day and tried the Pink Elephant. It reminded me of an elegant Bramble with the alliance of gin and blackberries. There is also a Hemingway daiquiri inspiration there with the lime, maraschino and grapefruit combination.
It called for blackberry liqueur, I subbed blackcurrant syrup (blackcurrants taste similar to blackberries but are very tart and have a slightly tannic flavor that I always loved). You really need a juniper-forward gin like Tanqueray for this to really work. And it works - it is a simple yet really great drink.
