The Ferengi spore pie was a type of pie.
In 2370, a picture of this pie was on display in the replimat of Deep Space 9. (DS9: "The Homecoming")
This food item was given a name in the Star Trek Encyclopedia, 4th ed., vol. 1, p. 266. Scenic artist Doug Drexler created the image for the pie, which was installed on a wall of the replimat. The reference work stated that this food item was avaiable at the replimat.
Although the (extra-canonical) name would seem to imply that this is a Ferengi dish, only a few episodes later "Rules of Acquisition" established that the replimat did not have a Ferengi menu
