A traditional martini is made with gin and vermouth, garnished with either an olive or a lemon twist. During Prohibition, martinis became extremely popular because gin was so easy to make. There are plenty of clever ways to put a modern twist on this classic martini cocktail. Add a dash of orange bitters, lemon juice, and basil, or espresso to a simple martini for distinct flavor, or make a major change by swapping sake, vodka, or rose water for the gin. Whether you need to make a party-sized martini or just want some cocktail advice, the Food & Wine guide to martinis has everything you need.
