Orange

A name that became a color

In English, the color “orange” was named after the fruit, not the other way around. Before oranges arrived in medieval Europe, the color was called yellow-red (Old English ġeolurēad). The word “orange” comes through Sanskrit nāraṅga → Persian nārang → Arabic naranj → Spanish naranja → Old French orenge → English. The color got its English name in the 1500s.

A hybrid origin

Sweet orange isn’t a single ancestral species. Genetic analysis shows it’s a cross between pomelo (Citrus maxima) and mandarin (Citrus reticulata), most likely arising in southern China several thousand years ago. The bitter orange is a separate but similar hybrid, with more pomelo influence.

The navel inside

Cut a navel orange and look at the bottom: there’s a small undeveloped second fruit growing inside. The “navel” is the partially-formed twin sticking out of the bottom of the larger fruit. Navels are also seedless, propagated entirely by grafting. Every navel orange tree in the world descends from a single mutant tree discovered in Brazil in the 1820s.

Bitter for marmalade

Marmalade — the British breakfast preserve made famous by Paddington Bear — is traditionally made from Seville oranges. The bitter peel and high pectin content of Sevilles produces the firm, intensely flavored set that distinguishes proper marmalade from sweet jam. Seville oranges are essentially inedible raw.

The OJ industry

Orange juice as a daily American breakfast staple is largely a 20th-century marketing invention. Surplus oranges in 1920s Florida combined with the discovery of frozen concentrate technology (perfected in the 1940s for wartime troop rations) made OJ a year-round commodity. Today, almost all commercial OJ is reconstituted from concentrate or has its naturally-occurring volatile aromas removed during pasteurization and added back from “flavor packs” — engineered to give a consistent taste regardless of season.
