Biriba

Rollinia mucosa

Long before biriba ever left the Amazon, it was a market-day treasure in Brazil, prized for a custardy, lemon-meringue sweetness that made it a favorite trailside and riverside snack. Amazonian and Brazilian households have traditionally eaten the ripe fruit as a refreshing, nourishing treat believed to settle the stomach and lift flagging energy after a long day of work in the heat. Because the fruit bruises and spoils within a day or two of ripening, it rarely traveled far from where it grew, which kept it a beloved regional secret rather than a widely known global fruit. It remains, to this day, a fruit people speak of the way they speak of a favorite grandmother's cooking, something tied to a particular place and season.

Safety.

The ripe fruit is a safe, widely eaten food, but the seeds are toxic if crushed or chewed and should never be eaten; the leaves and bark are not well studied for internal use.
