What is Pequi and what is it for?

What is pequi

Brazilian Caryocar is the scientific name of this strange fruit called, pequi or souari nut.  Pequi is derived from the word “pyqui” which means shell and hawthorn. It is a plant-flower species from Cerrado, Brazil.

Other names given to this fruit are thorny chestnut, piqui, cashew and jigua. The souari nut is a typical and popular fruit of some states of Brazil, such as Minas Gerais and Goiás.

The fruit is not only used in the culinary art of this extraordinary country but also widely used medicinally by the indigenous tribes of the Cerrado region.

These indigenous people are an important key to spreading this plant since they were the ones who planted the pequi around their villages when deforestation in the Brazilian savannas was at its greatest point of environmental destruction.        

Origin and current growing

As we already mentioned this fruit comes from Brazil, specifically from Cerrado, which is a natural region that covers a very large part of the country, but it also grows in small parts to the northeast of Paraguay, and the east of Bolivia.

Since the last decade, an indigenous tribe called Kisêdjê has been in charge of planting, caring for and harvesting pequi trees.

The tree is not so demanding in terms of soil, it can germinate as long as it is good soil. The fruit needs sun and moisture to grow healthy and strong.  

The pequiseiro (pequi tree) blooms from June to October and bears fruit from August to January. 

The fruit of the pequi lasts for 3 to 5 days when the skin begins to soften, and they are usually harvested from the ground.
