Shoot serial we hear that's enjoyed by cinema-goers (7)
I believe the answer is:
popcorn
'shoot' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for popcorn that I've seen before include "Exploded maize" , "Stuff to eat at the cinema" , "making a meal of it?" , "Heated maize kernel" , "Kernels exploded by heat" .)
