Taspar eggs were eggs that originated from the Cardassian creature called a taspar. Taspar eggs could be eaten boiled or raw. Most Cardassians were revolted by the sight of live taspar; it had a brownish color and a gelatinous consistency.
Several years later, in 2369, Gul Madred served a live taspar egg in a similar manner to a captive Captain Jean-Luc Picard in an effort to degrade him. Picard, however, refused to give in to Madred, and ate the raw Taspar, much to Madred's amusement. (TNG: "Chain of Command, Part II")
