Cajuína is a Brazilian beverage made from cashew fruit (cashew apple). The drink originated in the northeast of the country, and it is typically associated with Piauí and Teresina, though it is enjoyed in other parts of Brazil.
It is made with clarified and filtered cashew juice. The resulting liquid is pale golden due to the natural caramelization of sugars that occurs during sterilization, and it has a sweet and subtly tart flavor. Cajuína was traditionally produced as a non-industrial drink, but nowadays, there are several factory-produced versions.
