“Lychee is one of our favorite flavors for spring and summer, and very underused on menus,” says Kevin Diedrich, owner of San Francisco’s Pacific Cocktail Haven. In Diedrich’s lychee vodka cocktail, Lime in da Coconut, the summer fruit mingles with coconut, lime, and pistachio. “All together, the flavors are salty, tropical, and creamy," he says.
