Cocktails with Pineapple juice
Pineapple juice is the sweet-tart juice pressed from ripe pineapple flesh, used fresh or from carton in tiki and tropical cocktails.
Substitutes for Pineapple juice
Anything else fills the glass and gives up the head: fresh pineapple foams because of its own proteins, and nothing else in the fridge does that without egg white. Sweetness is the other variable — every substitute is sweeter, so the syrup in the recipe comes down.
Often confused with
Canned pineapple juice
Heat-treated: sweeter, flatter and free of the enzyme that makes fresh juice awkward around dairy. It also will not build a head, which is half of what fresh juice was for.
Pineapple purée
The blended flesh, thick enough to give a drink body, and juice lengthens and purée fills; swapping them by volume changes the texture completely.
Storage
Fresh juice separates within the hour, so stir the jug before every pour, and it ferments within a day or two even refrigerated. A carton keeps to its date and belongs in the fridge once open, where it also loses its foam within a few days.
