For Grandpa’s “Evening Cocktail”, pour rum, coconut liqueur and cold pineapple juice into a glass.
Stir once with a long spoon and carefully pour in the blackberry liqueur.
Enjoy Grandpa’s “Evening Cocktail” ice cold.
Preparation Tip:
Instead of the pineapple juice, canned pineapple can be pureed for Grandpa's "Evening Cocktail" and infused with some orange juice, then the cocktail will be a bit more creamy.
