1 c. sugar
2 ripe med. bananas, cut up
3 c. unsweetened pineapple juice
1 (6 oz.) can frozen orange juice concentrate
2 tbsp. lemon juice
1 (1 liter) bottle carbonated water or lemon lime carbonated beverage, chilled

Stir together sugar and 2 3/4 cups water until sugar dissolves. In a blender container combine bananas, half of the pineapple juice, and the orange juice concentrate. Cover, blend until smooth. Add to sugar mixture. Stir in remaining pineapple juice and lemon juice. Transfer to a 13 x 9 x 2 inch baking pan. Freeze for several hours or until firm. To serve, let mixture stand at room temperature for 20 to 30 minutes. To form a slush, scrape a large spoon across the frozen mixture. Spoon into a punch bowl. Slowly pour carbonated water down the side of the bowl. Stir gently to mix. Makes 23 (about 4 oz.) servings.
