I make this fun and refreshing drink every 4th of July. It starts out with a slush base. The bitters off-set the sweetness just the right amount, and it's a beautiful color. Can be served in a punch bowl, or individual servings. Garnish with cherries, orange slices or other desired fresh fruit.
To serve as a punch for a group - spoon or pour punch base into large punch bowl. Add ice and a 2 liter bottle of soda. Mix gently.
