So famous is Ernst Hemingway’s passion for a good drink that Philip Greene wrote a book about it , which explores Papa’s drinking habits and the drinks that appear into his books. Hemingway loved martinis and created his own version called “The Montgomery”, named after Sir Bernard Law Montgomery, the British general who would not go into battle unless he outnumbered his opposition by 15 to 1, the ratio of gin to vermouth that Hemingway used in his martinis. Hemingway preferred his cocktails icy-cold and reportedly had a clever hack for making “the coldest martini in the world.” His trick? Freezing water in tennis ball tubes to make massive ice cylinders. He also froze the glasses and the Spanish cocktail onions he used as garnishes.
