What is the plural of daiquiri?

For our Blue Crush party, the house drink was the frozen daiquiri, adapted very loosely from Mark Bittman, but with less rum (to accommodate our guests who had to work the next day), and frozen limeade from concentrate substituting for fresh-squeezed lime juice and sugar.  We made pretty good work of a full pitcher.

Ingredients:

4 cups frozen strawberries
1 12 oz. container frozen limeade from concentrate
1 cup rum (Bacardi dark rum works well, but it probably doesn't matter)

Recipe:

Place ingredients in cuisinart or blender.  Puree.  Pour (carefully) into pitcher.  Drink.  Little paper umbrellas optional.
