Cocona
Solanum sessiliflorum · Solanaceae · also known as Cubiu, Topiro, Peach tomato, Orinoco apple
An Amazonian relative of the tomato and naranjilla — glossy orange fruit with a tomato's body and a citrus-lime tang, cooked into savory sauces and sweet drinks across the rainforest. Neither fruit nor vegetable, and used happily as both.

Cocona sits right on the fruit-vegetable border — an Amazonian Solanum used as juice one meal and as savory sauce the next, exactly as its cousins the naranjilla and tomato are.

How to select & store
Picking a ripe one
Choose firm fruit that has turned fully orange-red with taut, glossy skin and a fine fuzz when fresh. Green shoulders mean underripe and extra-sour; soft or split fruit is past.
Storing it
About a week refrigerated, a few days on the counter — sturdier than a tomato thanks to its thick skin. The pulp freezes well for drinks and sauces.
Practical uses
🍽️ Culinary
- Blended with water and sugar into refrescos and juices across the Amazon
- Cooked into savory sauces, salsas, and stews like a tangy tomato
- Chutneys, jams, and hot-sauce bases from the acidic pulp
- Stuffed and baked, or sliced raw into salads with salt and chili
🌿 Health & traditional
- Long used by Amazonian peoples (notably in Brazil's Cubiu tradition) for cholesterol, blood sugar, and skin
🎎 Cultural
- A staple garden fruit of Indigenous Amazonian communities, grown from Peru to the Rio Negro
- Close kin to the naranjilla (lulo) and the tomato — a Solanum that straddles the fruit-vegetable line
Eating cocona: what to know
What regular consumption looks like
Cocona is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Cocona contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The cocona refuses to pick a side. Botanically it’s a Solanum — cousin to the tomato and the naranjilla — and it behaves like both a fruit and a vegetable depending on the cook. Blended with sugar and water it’s a bright rainforest refresco; simmered with onion and chili it’s a tangy sauce. Amazonian gardens have grown it, undecided and unbothered, for a very long time.
Tomato body, citrus soul
Cut one and it looks like a firm orange tomato; taste it and the lime arrives — a clean, savory sourness with just enough tropical sweetness to work in a drink. The thick skin makes it sturdier than a tomato (it actually keeps a week in the fridge), and the flesh holds up to cooking without collapsing, which is why it moonlights so easily as salsa, chutney, and hot-sauce base.
The Amazon’s everyday fruit
From the Peruvian selva to Brazil’s Rio Negro (where it’s cubiu), cocona is a dependable dooryard staple — productive, year-round, and endlessly useful. Indigenous communities have long eaten it not just for flavor but as functional food, with a folk reputation for helping manage cholesterol and blood sugar that modern researchers have begun to probe.
Cooking with it
Treat cocona as a sour tomato that wandered into the fruit bowl. For a drink, blend the pulp with water, sugar, and a squeeze more acid isn’t needed — it brings its own. For the kitchen, cook it into salsas and stews, or pair it with fellow Amazonians naranjilla and camu-camu for a rainforest sour trio.
