Squeeberry

A small purple berry that grows on thorny bushes and is notorious for its sour taste. They grow mostly in the forests of Elbrith, though they have also been found in some of the woodlands of the Etherean interior. Their juice is sometimes used as an additive in winter ales and wines, but their tartness makes them unsavory in deserts. Children will sometimes challenge each other to see how many they can stand eating raw.
