Morphology
A B1 learner who knows 'jam' and 'tomorrow' will most likely read this literally as 'jam in the future' and will not infer the idiomatic sense of a perpetually postponed or unlikely benefit. The established, culturally specific meaning ('an empty promise' or 'always postponed benefit') cannot be predicted from the constituents and is therefore an idiom that learners need to encounter, making it opaque.
Etymology
Jam tomorrow comes from Lewis Carroll's book, where a character is told she can have jam tomorrow but never jam today, so the sweet treat is always put off. That's why people now use it for a 'promise' of good things later that is unlikely ever to happen.
