TEALA'S MANGO MARGARITAS
Source: Texas Monthly

Teala's tomatoey salsa and pico de gallo-spiked black bean dip are lively complements to the cooling cocktails.

1 cup white tequila
1/2 cup Triple Sec or Cointreau*
2 1/2 cups pureed fresh ripe mangoes (4 or 5, depending on size)**
1/4 cup fresh lemon juice
1/2 cup fresh lime juice
1/4 cup fresh orange juice
1 pound crushed ice

Place half of the ingredients in a blender (it can hold only half the batch at a time) and blend to a slushy consistency (will not be as thick as a typical frozen margarita).

*If mangoes are not fully ripe, add more Triple Sec to taste.

**Off-season, use frozen mangoes.

Makes four 10-ounce margaritas

Sorry, I couldn't find it on the Internet but this one was discussed on the some of the boards as good.
