Chocolate cordial is a loosely defined chocolate-flavoured sweetener whose name is applied inconsistently across confectionery, non-alcoholic concentrates, and liqueurs.
Thick and syrupy on the palate, finishing sweet and long with a rounded chocolate flavour and only a faint bitter edge.
Bartenders pour it in a small measure to sweeten and add chocolate flavour, treating it as a sweet flavouring concentrate rather than a flavour-only additive.
Because the name covers several distinct products, no single reliable swap exists; where it supplies only a sweet chocolate accent, the sweetness and syrupy body can be rebalanced with a neutral sugar syrup carrying a chocolate flavouring, but where it carries the drink's primary flavour the correct substitute depends on which sense of 'cordial' is meant.
Chocolate liqueur
A liqueur such as crème de cacao is an alcoholic, sweetened spirit; a cordial in the sweetener sense is a non-alcoholic sweetened concentrate. In US drinks usage 'cordial' is itself a synonym for liqueur, which is the source of the confusion.
Chocolate cordial confection
The confection is a solid chocolate-shelled sweet with a liquid centre, not a pourable syrup or drink ingredient; searches for 'chocolate cordial' most often return this cherry-cordial style candy.
The term does not resolve to one stable product. In its sweetener sense a cordial is a sweetened flavouring concentrate; in confectionery it names a chocolate-shelled sweet with a liquid centre; and in US drinks usage 'cordial' is a synonym for a sweetened liqueur. As a bar syrup it would be a sweet, chocolate-flavoured concentrate with a syrupy body.
