Used in making her kind of pickle? (7)
I believe the answer is:
gherkin
'pickle?' is the definition.
(gherkin is a kind of pickle)
'used in making her kind' is the wordplay.
'used in' says the answer is hidden in the clue.
'GHERKIN' is hidden within 'making her kind'.
'of' acts as a link.
(Other definitions for gherkin that I've seen before include "Cucumber - London skyscraper" , "often pickled" , "Small cucumber, usually pickled" , "Small cucumber pickled whole" , "Salad vegetable - City of London skyscraper" .)
