Dark and Stormy

Named for the dark clouds swirled up by the dark rum, this one's sweet-with-an-edge. Ginger beer is a non-alcoholic, spicier version of ginger ale; use the fieriest one you can find to stand up to the rum.

Tomato Martini

When it's just too warm out for a Bloody Mary, this is where to turn: tomato water gets you the essence of tomato flavor without the heaviness of juice. Pair with grilled oysters, corn on the cob, and boat shoes.
