This lemony, tangy drink gets sweeter, and prettier, as the cubes melt. My daughter, Emma, loves picking out the mint sprig and eating the leaves.
Pour the juice concentrate and 1 can of water into a pitcher. Mix to combine, then pour the juice into two ice cube trays, adding raspberries or sliced strawberries if you wish. Freeze.
Combine the 2 quarts of water and the sugar in a medium saucepan. Bring to a boil and stir to combine. Reduce to a simmer and cook until the sugar is dissolved, about 1 to 2 minutes. Remove from heat.
Strain the lemon juice through a fine sieve into the sugar syrup. Chill. Slit each lemon slice once, from center to rind, then press the slits onto eight glasses. Fill each glass with 3 berry ice cubes and the lemonade. Garnish with a mint sprig. Makes 8 glasses.
