Ingredient of salad and stew carers prepared (10)
I believe the answer is:
watercress
'ingredient of salad' is the definition.
(watercress is a common salad ingredient)
'stew carers prepared' is the wordplay.
'prepared' is an anagram indicator.
'stew'+'carers'='stewcarers'
'stewcarers' with letters rearranged gives 'WATERCRESS'.
'and' acts as a link.
(Other definitions for watercress that I've seen before include "bit of salad" , "Salad plant" , "salad ingredient" , "low-calorie food" , "Salad vegetable" .)
