First, a language lesson: Ramu means “rum” in Japanese.

That sugarcane-based spirit is the largest single ingredient in Hojoko’s Ramu Swizzle, a punchy cocktail that also features lemon juice, passionfruit, and both yellow and green chartreuse.

Its most interesting asset might just be a passionfruit-honey syrup, which adds a decidedly tropical note to the concoction. Hojoko co-bar manager Joe Cammarata uses Dafruta passionfruit concentrate (find it at a local bodega). The syrup is cold-processed; making it requires no cooking.

A final callback to Hojoko’s Japanese influence is the drink’s shiso leaf garnish, which lends a fresh, spicy aroma. Shiso can be found at most Asian grocery stores and Whole Foods, Cammarata notes, but rosemary or mint can be subbed in a pinch.

Sweet and sour, fruity and herbal, the Ramu Swizzle is a bit of everything—and precisely what you want in-hand peak summer.
