This step called for placing a "small block of ice" in a punch bowl and then pouring the punch over it. You then add additional ice and pour in the carbonated water when you are ready to serve.I suggest adding a small bag of ice to a punch bowl, adding your punch and then carbonated soda just before party time.
If you want to keep this in the refrigerator, keep the punch and carbonated soda separate until ready to drink. Then mix a glass at a time.
*It's really hard to go wrong with the amount of pineapple. It doesn't have to be exact and can be increased or decreased based on preference.**I'm assuming this should be Maraschino cherries. If not, be sure to pit the fresh cherries before use.***The recipe did not distinguish if the lemon was an ingredient IN the punch or a garnish. I zested the lemon, added the lemon zest and the sliced lemon to the blender.
