Citrus Water Punch
2 tablespoons citric acid (you can find this at most pharmacies or natural food stores)
5 quarts water
2 cups sugar
2 tablespoons pure lemon extract
3 sliced lemons
3 sliced limes
In a large pitcher or punch bowl, stir water, sugar, citric acid, and lemon extract together. Add sliced fruit and ice.
A note from Melanie: *Note: as mentioned by commenters (and I’ve received emails about it), if you have leftover punch, remove the sliced limes and lemons before refrigerating. The limes and lemons will give the punch an overly sour acidic taste if the punch is stored overnight that way.
