Jam

Jam is an food preserve usually served at breakfast.

In 2152, while stranded on a moon with an Arkonian pilot, Commander Tucker joked that the Captain would demote him to steward for crashing a shuttlepod and that he would have to ask him if he wanted jam or marmalade with his breakfast. 

In a Section 31 holoprogram, Doctor Julian Bashir ordered moba jam along with hot buttered scones and red leaf tea for breakfast.
