A papaya is the fruit of one tropical tree, and a mango is the fruit of a different tropical tree; they are not related species, even though both have sweet, orange flesh. A useful memory hook: papaya has a soft, custardy inside with a hollow full of black seeds, while a mango has a large flat stone in the middle, like a stringy version of a peach.
The core difference
Papaya and mango are different tropical fruits from unrelated trees, distinguished mainly by their seeds and texture.
- papaya — a tropical tree or its sweet, orange-fleshed fruit, with a hollow centre full of small black seeds: She sliced a ripe papaya for breakfast.
- mango — a tropical tree or its sweet, juicy orange-fleshed fruit, grown around a single large flat stone: She sliced a ripe mango for the fruit salad.
How to tell them apart
The easiest way to tell papaya and mango apart at the table is by what is in the middle. Cut a papaya in half and you will find a hollow lined with rows of small black seeds, almost like a melon. Cut a mango and you will hit a single large, flat stone that the flesh clings to, often in stringy fibres near the skin.
The confusion tends to come up in recipes and fruit salads, where both are described simply as "tropical" and "orange-fleshed," without saying which one is meant. Their names hint at their separate origins too: mango traces back through Portuguese to a South Indian word first used in English for the fruit in the 1580s, while papaya comes from Spanish and, further back, an Indigenous Caribbean word.
