Cajuína is a unique drink from the Northeast region of Brazil, but it can also be found in Rio de Janeiro. It is made from the juice of the cashew fruit, which is then sweetened and pasteurized. Cajuína has a distinct flavor that is both sweet and slightly acidic. It is often enjoyed as a non-alcoholic beverage and pairs well with traditional Brazilian dishes. You can find Cajuína in specialty stores or restaurants that serve Northeastern cuisine.
