Pineapple

A multiple fruit

A pineapple is technically a multiple fruit — what looks like a single fruit is the fused-together result of dozens of individual flowers on a single inflorescence. Each “diamond” segment of the surface is one of those original flowers. The crown of leaves at the top is a vegetative rosette that can be replanted to grow a new pineapple plant.

A long road to ripe

Pineapples take 18–24 months from planting to first fruit. Each plant produces one main fruit, then several smaller “ratoon” crops if left in the ground for additional years. They thrive only in tropical conditions; commercial production concentrates in Costa Rica (the largest exporter), the Philippines, Thailand, and Hawaii.

Bromelain — the mouth tingle

Pineapple contains bromelain, a protease enzyme that breaks down proteins (similar to papain in papaya). When you eat raw pineapple, the bromelain literally starts digesting the soft proteins in your mouth — that mild stinging sensation. It’s also why fresh raw pineapple can’t be set in gelatin (digests the gelatin) and why pineapple is a traditional meat marinade. Cooking destroys the enzyme; canned pineapple has no bromelain activity.

A status symbol

In 17th- and 18th-century Europe, fresh pineapples were rare and ferociously expensive — a single fruit could cost the modern equivalent of thousands of dollars. They became status symbols at aristocratic dinners, sometimes rented (not eaten) just to be displayed. The pineapple motif on furniture, gateposts, and architecture dates from this status-symbol era as a sign of welcome and hospitality.

A 19th-century industrial fruit

Captain James Cook introduced pineapples to Hawaii in the late 1700s. By the early 20th century, James Dole’s Hawaiian Pineapple Company industrialized canning and made pineapple a global commodity for the first time. Hawaii produced the majority of the world’s pineapples until the 1960s, when production shifted to lower-cost Asian and Latin American markets.
