pineapple
Also known as: pineapple chunks
A tropical fruit with sweet-tart, very juicy yellow flesh under a spiky rind, eaten fresh, grilled, or canned, and used in both sweet and savory dishes. It contains bromelain, an enzyme that breaks down protein -- useful for tenderizing a marinade, but also the reason fresh pineapple can keep gelatin from setting.
Buying guidance
A ripe pineapple smells sweet and fragrant at the base, not the crown, and gives slightly to gentle pressure; a fermented or sour smell means it's overripe. Color is a weak ripeness signal, since some varieties stay green-gold even when fully ripe -- smell and give are more reliable. Canned pineapple has been heat-processed, which destroys the bromelain enzyme, so it won't tenderize meat the way fresh pineapple does.
Substitutions
- Canned pineapple, drained -- convenient and consistent, but loses the enzyme once heat-processed.
- Mango -- comparably sweet and juicy but lacks pineapple's tartness and enzyme activity.
- Fresh peach -- milder sweetness and softer texture, with no acidity or enzyme effect.
Tips & common mistakes
Because bromelain keeps working the whole time raw pineapple is in contact with meat, a marinade left too long can turn the surface mushy and mealy instead of just tender -- a short marinade time is enough, and longer isn't better the way it can be with other acidic marinades.
Storage
A cut pineapple ripens very little further once cut, unlike some fruits, so cutting an underripe one early won't help it along -- let it ripen whole at room temperature first, then refrigerate only after cutting, in a sealed container so its strong aroma doesn't spread to other food nearby.
