Sangria

All the fruit your heart desires (mango is particularly good in here)
Juice of 1 orange ~1/2 cup (probably easiest to just buy OJ
¼ cup granulated sugar (I like to use superfine sugar)
¼ cup Triple Sec
One 750 ml. bottle inexpensive, fruity, medium-bodied red wine, chilled

put the sangria back in the OJ and wine containers (with funnel)
Serves 4 - so for a party of 80 people, multiply by 20!
