Good relatives eating the woman’s pickle (7)
I believe the answer is:
gherkin
'pickle' is the definition.
(gherkin is a kind of pickle)
'good relatives eating the woman's' is the wordplay.
'good' becomes 'g' (abbreviation).
'relatives' becomes 'kin' (I've seen this before).
'eating' is an insertion indicator.
'the woman's' becomes 'her'.
'g'+'kin'='gkin'
'gkin' enclosing 'her' is 'GHERKIN'.
(Other definitions for gherkin that I've seen before include "La traviata composer" , "Cucumber - London skyscraper" , "Salad vegetable - City of London skyscraper" , "Vegetable of the cucumber family" , "Small cucumber, usually pickled" .)
