Cordials are a traditional after-dinner drink and can be served on their own or with a cup of coffee (or mixed with the coffee) to round off a meal. Some of the more exotic cocktails, such as Stingers and Grasshoppers, also have cordials as an ingredient.
Well-known brand names and their flavors include:
Grand Marnier (orange)
Sambuca (black licorice)
Southern Comfort (peaches)
