Alva

An alva is a fruit that grows all over Bajor.

Dried alva was part of the staple diet of the Ornathia resistance cell during the Occupation as it warded off infection. 

In 2374, the $𝜇$ of the mirror universe ate alvas on Deep Space 9. Bareil greatly enjoyed the fruit, which he told Kira Nerys did not grow on the alternate universe $𝜇$.
