Pomegranate syrup is a sweetened, thick red syrup flavoured with pomegranate juice, used to sweeten and colour drinks.
Deeply fruity and sweet, carrying the tangy-red character of pomegranate with a medium acidity beneath the sugar. The molasses form is markedly tart and only faintly sweet.
A small measure sweetens and tints a build a vivid red; it is stirred or shaken into the mix as a sweetener and colourant rather than dosed heavily. Its viscous body means it settles unless integrated. The tart, unsweetened molasses form plays the opposite role, contributing souring rather than sweetness.
A sweetened pomegranate syrup of the grenadine type is the closest match, sharing sweetness, red colour and pomegranate character; a raspberry syrup can stand in for sweetness, body and colour but replaces the pomegranate aroma with its own, and neither can supply the souring role of the tart pomegranate-molasses form.
Classic grenadine is itself a sweetened pomegranate syrup, so the two overlap heavily and are often interchangeable behind the bar; modern commercial grenadine, however, is frequently flavoured artificially or with mixed fruit and defined by its sweet cocktail role rather than genuine pomegranate depth.
Pomegranate molasses
Pomegranate molasses is pomegranate juice reduced to a tart, minimally sweetened concentrate used as a savoury souring agent, whereas cocktail pomegranate syrup is sweet and used for sweetness and colour.
In its cocktail form it is produced by combining pomegranate juice (Punica granatum) with sugar to yield a sweet, viscous, deep-red syrup — the same product classically sold as grenadine. A separate culinary product also called pomegranate syrup, better known as pomegranate molasses, is instead pomegranate juice reduced by boiling into a thick, tart concentrate with little or no added sugar.
A sugar solution made from oxidising juice, it is refrigerated once opened and has a limited shelf life.
The reduced pomegranate-juice form, pomegranate molasses, is a staple of Middle Eastern and Iranian/Levantine cooking.
