Longana

Longana refers to a small, unripe green mango used in Filipino cuisine. These mangoes are distinct from the mature, yellow mangoes that are typically eaten as a sweet fruit. Longana mangoes are highly acidic and tart. They are often eaten dipped in bagoong (fermented fish or shrimp paste) or salt. They can also be pickled or used as a souring agent in dishes like sinigang. The term "longana" may sometimes be used interchangeably with other words for unripe mango depending on the region, though subtleties may exist in the specific variety or level of ripeness implied.
