Chocolate syrup is a sweet, cocoa-flavored syrup, thin and pourable, used as a flavoring and sweetening condiment.
Pronounced cocoa aroma over a strongly sweet body, with only a low background bitterness and a medium, coating texture.
A drizzle sweetens and adds chocolate flavor at once, so it shifts a drink's sugar balance as well as supplying cocoa notes; because the purchased form is heavily sweetened, it is dosed sparingly and shaken or stirred through the build, and it also serves to line or decorate a glass.
Another cocoa-based product supplies the essential chocolate aroma and colour — chocolate sauce, or cocoa powder loosened with simple syrup; any shortfall in sweetness can be rebalanced with added sugar syrup, but the cocoa note cannot be replaced by a non-chocolate ingredient.
Chocolate sauce
Chocolate syrup is a thin, pourable, largely fat-free cocoa-and-sugar liquid, while chocolate sauce is richer and thicker, typically made with melted chocolate and/or dairy fat such as cream or butter. The two names are often used interchangeably, but they differ in fat content, body and pouring behaviour.
Cooked from cocoa powder, a sweetener of sugar and/or corn syrup, and water into a pourable liquid, it draws its chocolate character from cocoa rather than melted chocolate. Unlike chocolate sauce, it is generally made without significant dairy or added fat, which keeps it thin and largely fat-free.
