Combine all the ingredients in a pitcher. Use a wood spoon to stir. Fill the pitcher with ice and add a few garnishes.
For a single cocktail, combine all ingredients, except the grenadine, in a cocktail shaker. Fill with ice and shake 15 seconds or until cold. Pour over ice and serve with a splash of grenadine on top.
Notes
Make Ahead: The punch can be made several hours before serving. Keep in the fridge until you are ready to serve.
