This margarita is the result of painstaking research. We can guarantee that quality tequila is definitely required. (Cheap tequila carries a hint of turpentine with a paint stripper after-taste.) Grand Marnier makes a far better margarita than either Triple Sec or Cointreau, though Blue Curaçao makes a colorful change. Don't even think of touching a margarita mix or a commercial sweet and sour mix. They are mostly corn syrup. Squeeze your own fresh fruit, the real thing tastes so much better.
5oz fresh squeezed lime juice (approx. 4 limes)
3oz fresh squeezed lemon juice (approx. 2 lemons)
2oz simple syrup
8oz quality tequila (e.g. Sauza Hornitos or Sauza Conmemerativo)
3oz Grand Marnier
Simple syrup is made by combining equal parts sugar and water, heating to a boil until sugar is dissolved and then cooling.
Mix ingredients. Shake with ice cubes. Serve in frosted and salted glass.
Makes 4 glasses margarita -- just enough for a pleasant evening for two.
