pomegranate juice
Juice pressed from pomegranate seeds, deep red, fruity, tart and slightly astringent.
Pure, unsweetened pomegranate juice is sold in many supermarkets alongside the other juices, and more reliably in Turkish or Middle Eastern grocers and health food shops. Sweetened juice drinks or blends are too sweet and too flat. It should also not be confused with pomegranate syrup or pomegranate molasses, which are cooked down and far more concentrated.
Substitute:
The best option is to press fresh pomegranate seeds yourself, which tastes even fresher. At a pinch, pomegranate molasses thinned with water will do, but it brings a darker, caramel-like note.
