Jam, yes; but not much butter (6)
I believe the answer is:
scrape
'jam' is the definition.
(both can mean a difficult situation)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scrape that I've seen before include "Difficult predicament" , "Capers (anag.)" , "Graze - awkward predicament" , "Grate, scratch" , "Slight injury - close shave?" .)
