Don't use regular ice cubes to keep the Halloween punch chilled, creep-out your guests with a frozen hand in the punch! There are 2 simple options to this recipe:
Recipe # 1
Add the food coloring to the water, mix, and pour into the glove. Tie it off tightly with the twisty or rubber band. Place on a flat surface (that will catch any drainage) and freeze the glove until it's solid. Remove the glove and place in the punch before serving.
Recipe # 2
This option is simple but it's going to match the color of your punch -- because all you need to do take some actual punch and freeze it in the glove. This option is tastier than frozen hand recipe #1 since the punch will not dilute when the hand melts.
Another variation of this is to simply freeze some Squirt or Mountain Dew into the glove, which adds a more realistic look to the hand. Make sure the flavor compliments the punch.
