West Indian acai skins in a tin of preserves (8)
I believe the answer is:
jamaican
'west indian' is the definition.
(I know that Jamaican is a type of west indian)
'acai skins in a tin of preserves' is the wordplay.
I cannot quite see how this works, but
an anagram of 'acai' is 'aica' which is within the answer.
'a' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for jamaican that I've seen before include "Eg, native of Kingston" , "Bob Marley, for instance" , "Caribbean inhabitant" , "One from Kingston, say" , "Caribbean island resident" .)
