The original Daiquiri was a mixture of rum, lime, and sugar served over ice. Born in Cuba, the Daiquiri was introduced to America by Admiral Lucius W. Johnson of the U.S. Navy who discovered it in his travels. Johnson brought the Daiquiri recipe back to the Army and Navy Club in Washington DC where it became a favorite of many young Naval officers, including a young John Fitzgerald Kennedy. Thanks to Roosevelt's Good Neighbor Policy, which opened up trade to Cuba and the Caribbean, when wartime rationing made whiskey, gin and vodka hard to come by in the 1940s, Cuban rum became a popular substitute and the Daiquiri then began to appear in American bars throughout the country.
Most people today are more familiar with the frozen, fruit blended versions and, though I do like a well prepared classic Daiquiri, I'm not a bit adverse to adding fruit to Daiquiris myself. So, when I was given a huge bag of frozen blueberries recently, a Blueberry Daiquiri seemed a perfect way to make use of them!
