Before serving, add the water and sparkling cranberry apple cider. Stir. Finally, it’s time to chill your punch with ice. If you’ll be serving this punch slowly over the course of a couple hours, use a large block of ice so as to not to over-dilute your punch. If you’ll be ladling out the punch all at once, fill the punch bowl about halfway with ice cubes for a quicker chilling and dilution process.
