If you can't find ripe mangoes, you could also use peaches instead.
2 cups fresh mango (chopped ~ about 2 large mangos)
1 (12 oz) can frozen lemonade or limeade, thawed
1 quart Club Soda (water can be used too)
1-1/2 cups orange juice
1-1/2 cups tequila
1/2 cup Triple sec
3 lemons, sliced
In a food processor, blend mangoes with lemonade concentrate until smooth. In a large pitcher or bowl, combine mango mix with water, orange juice, Triple Sec and tequila. Float sliced lemons in punch, or garnish each glass with a slice.
