Keep some jam (8)

Ross

I believe the answer is:

preserve

I believe this is a double definition.

'keep' is the first definition.
(I know that keep can be written as preserve)

'some jam' is the second definition.
(jam is a type of preserve)

(Other definitions for preserve that I've seen before include "Refuse to give up" , "Keep - pickle - store" , "Keep (something) safe" , "Protect; jam" , "Keep alive; jam" .)

I've seen this clue in The Daily Express.
