Banana

The world’s most-eaten fruit, and one where the entire global export trade rests on a single sterile clone with no genetic defence against anything.

Where it comes from

Bananas were domesticated in New Guinea and Southeast Asia and spread to Africa very early — East African highland bananas are a staple crop with hundreds of local varieties. The seedless fruit is a sterile hybrid, propagated only from suckers.

Almost every banana in international trade is Cavendish, a single clone. Its predecessor, Gros Michel, was wiped out commercially by a soil fungus in the mid-twentieth century, and a new strain of the same disease is now moving through Cavendish plantations. A monoculture of clones has no variation for selection to work on, which is exactly the problem.

Varieties

• Cavendish — The export banana. Sweet, mild, and picked green to survive shipping.
• Lady finger / sugar banana — Small, thin-skinned, more intense.
• Red banana — Softer, faintly raspberry-scented.
• Highland cooking bananas — Matoke and relatives, steamed as a staple in East Africa.
• Plantain — Starchy cooking types, treated separately in the atlas.
• Banana leaf and flower — Not fruit, but food — leaves for wrapping and steaming, the flower as a vegetable across Southeast Asia.

In the kitchen

Bananas ripen after picking, which is unusual — they convert stored starch to sugar right through to black. A banana too ripe to eat is exactly right for baking, and no amount of added sugar substitutes for it.

They give off a lot of ethylene and are among the strongest ripening agents in a fruit bowl. Bagging a banana with hard avocados or peaches genuinely works.

Banana browns fast and does not stop. Acid slows it a little; nothing prevents it.
