Our family always makes this for large get togethers, baby showers and such. It's a lot less sweet than a traditional punch.
What you'll need:
2 T. Citric acid (You get this from the pharmacy of the grocery store. You have to ask for it at the counter.)
1 t. lemon extract
5 quarts water
2-3 c. sugar (to taste)
pellet ice (Sonic - you can use whatever ice you want, but if you are serving in a punch bowl pellet ice is the best)
2-3 lemons, sliced
2-3 limes, sliced
Mix citric acid, lemon extract, water and sugar. Add ice. Drop in maraschino cherries (they will sink to the bottom) and float lemons and limes on top.
