Ingredients

4 cups water 

3 cups sugar 

6 cups coarsely chopped strawberries 

2 cups coarsely chopped pineapple 

1 cup pineapple juice 

1 cup orange juice 

1 cup freshly squeezed lemon juice 

2 quarts seltzer water 

Preparation

Make a simple syrup: Combine the water and sugar in a large saucepan, and bring to a boil over medium-high heat. Cook 5 minutes. Remove from heat, and set aside until syrup is completely cool.

Transfer syrup to a large container. Add strawberries, pineapple, pineapple juice, orange juice, and lemon juice; gently stir to combine. Fill two ice-cube trays with punch, and place in freezer. Place remaining punch in refrigerator to chill.

When ready to serve, remove punch from refrigerator; add the seltzer water and frozen-punch ice cubes. If transporting, add the seltzer just before serving. Serve in a large bowl or individual glasses.
