Preferring your own stuffed pimentos (8)
I believe the answer is:
nepotism
'preferring your own' is the definition.
I can't judge whether this defines the answer.
'stuffed pimentos' is the wordplay.
'stuffed' indicates an anagram.
'pimentos' with letters rearranged gives 'NEPOTISM'.
Can you help me to learn more?
(Other definitions for nepotism that I've seen before include "Taking on family" , "The favouring of relatives or friends for jobs, etc" , "example of relative favouritism" , "Favouring family over others" , "Pro-family bias" .)
