Rasberry Ice Cubes:

Pour a can of berry juice concentrate into a pitcher. Add water according to package directions.

Stir with a spoon until well mixed. Pour mixture into two ice cube trays.

Add a raspberry to each section of the ice cube tray. Place trays in the freezer to make berry ice cubes.

Lemonade:

In a large pot, mix 2 quarts of water with 1⅓ cups of sugar. Stir the mixture and bring to a boil.

When mixture is boiling, reduce heat to simmer and cook until sugar is dissolved. About two minutes. Remove pot from the heat. 

Using a fine sieve, strain lemon juice into water/sugar mixture.

Place in refrigerator to chill. 

When ready to serve the chilled lemonade, place a lemon slice in each tall glass. Fill each glass with raspberry ice cubes and pour the lemonade over the top.
