Mix guava and lemon juices in a large bowl or pitcher. Chill for at least 2 hours. Just before serving, stir in ginger ale and seltzer. Serve in tall glasses over ice, garnished with lemon slices, if desired.
I loved this Guava Punch. It was quick and easy to make and tastes amazing. I will be enjoying this again and again. What a lovely blend of flavors. Made for Think Pink 2016. (BK)
