Umbu
Spondias tuberosa · Anacardiaceae · also known as Imbu, Brazil plum, Umbuzeiro fruit
The "sacred tree of the backlands" bears this lime-green, juicy-tart fruit through the droughts of Brazil's caatinga — thanks to water-storing roots. Umbu means "the one that gives drink," and the milkshake-like umbuzada proves it daily.

The umbu tree survives the desert on buried water tanks — root tubers that can hold hundreds of liters — which is why its name in Tupi means "tree that gives drink."

How to select & store
Picking a ripe one
Skin turning from green to yellow-green with a slight give — fully soft fruit is honeyed but fragile. Hard green umbu is for salted snacking and cooking, and locals buy it that way on purpose.
Storing it
A few days at room temperature, a week refrigerated. The harvest glut is pulped and frozen across the sertão, and umbu jam cooperatives have made shelf-stability a livelihood.
Practical uses
🍽️ Culinary
- Umbuzada — pulp blended with milk and sugar, the sertão's breakfast milkshake
- Eaten green with salt, or ripe out of hand under the tree
- Jams, jellies, and pulp for juices (women-led cooperatives export them)
- Sorbets and caipirinha variations in modern Brazilian kitchens
🌿 Health & traditional
- The tree's water-storing root tubers are an emergency water and folk-remedy source in drought lore
🎎 Cultural
- Euclides da Cunha called the umbuzeiro "the sacred tree of the sertão" — shade, water, and fruit in a land of thorn
- Umbu harvest is a communal income season in the caatinga; the fruit anchors agro-extractive cooperatives
In the thorn-scrub sertão of northeastern Brazil, where droughts are measured in years, one tree keeps a secret reservoir. The umbuzeiro stores water in swollen root tubers — hundreds of liters buried under the sand — and every summer it spends that savings on a crop of lime-green fruit so juicy its Tupi name means “the tree that gives drink.”
Umbuzada: breakfast of the backlands
The definitive preparation is disarmingly simple: ripe umbu pulp, cold milk, sugar, blender. Umbuzada is part milkshake, part morning ritual across Bahia and Pernambuco — tart fruit rounded by dairy into something like drinkable green-mango custard. The same pulp, frozen by women-led cooperatives in the caatinga, now travels to juice bottles and even European fair-trade shelves.
Green with salt, gold with patience
Like its cousins across the Spondias genus — Southeast Asia’s ambarella and the Philippines’ sineguelas — umbu is eaten at two stations: crunchy-green with salt for the pucker crowd, or dropped-ripe and honeyed for everyone else. The family resemblance to a tiny wild mango is no accident; they share the Anacardiaceae with it.
A conservation fruit
Umbu is gathered, not farmed — from wild trees that can live a century — and the harvest underwrites thousands of sertanejo families. Agroforestry groups treat the umbuzeiro as the caatinga’s keystone argument: a native economy that only works if the drylands stay alive. Eating umbu jam is, in a small way, voting for the thorn forest.
