Commercial grenadine syrups are usually made from corn syrup and flavorings, with little or no trace of pomegranate. Making your own grenadine is easy, and will make for superior libations.
bobbyperu explains how: You’ll need 2 parts 100% pomegranate juice to 1 part superfine sugar. Bring the juice to a simmer over medium heat and reduce by half. Reduce heat and add sugar, stirring until it’s dissolved. Cool to room temperature, and store in refrigerator. It will last quite a while, if kept refrigerated.
Anyone made grenadine?
