If fresh passion fruit isn't available, substitute 3 cups passion-fruit nectar, frozen in ice-cube trays, for the strained fresh passion-fruit puree and, when ready to blend, omit the ice cubes.

Ingredients

　　1 pound fresh passion fruit (about 12)

　　3 cups ice cubes

　　3/4 cup white tequila

　　1/4 cup sugar

　　Halve passion fruits and scoop pulp and seeds into a blender. Blend pulp briefly (seeds should still be in large pieces). Force fruit through a fine sieve into a measuring cup and discard solids. In a blender, blend 1/2 cup puree with remaining ingredients until smooth. Pour drink into 4 stemmed glasses.
