Kava nut

A Kava nut is a food enjoyed by the Vorta.

In 2375, Weyoun commented to Odo that Vorta only really enjoyed kava nuts and rippleberries and thought it was due to the Founders wanting the Vorta to remember their existence before they joined the Dominion. 

The mirror universe $𝜇$ also enjoyed kava nuts and rippleberries.
