This cocktail came about when my housemate and I were talking about sea-themed drinks, somehow we got onto the conversation of dolphins, and the rest is history. It's a refreshing cocktail, but without being too stereotypically summery.
25ml blue curaçao
20ml blueberry puree
15ml lime juice
50ml lychee juice
Shaken over ice, double strained, and served in a martini glass. And don't forget an escaped dolphin sweet for garnish!
