Brew the tea bag with 1/8 litre of boiling water, steep for 5 minutes and let it cool down. Halve the melon and remove the seeds with a teaspoon. Use a ball cutter to remove small balls from the pulp (or dice the pulp).
Mix lemon juice, raspberry syrup, well chilled apple juice, mineral water and mallow tea in a punch bowl. If necessary, place in the refrigerator for a few hours before serving. Add the melon balls and fill into glasses.
