In the caramel I tested the cream (5)
I believe the answer is:
elite
'cream' is the definition.
(as in the cream of the crop)
'in the caramel i tested' is the wordplay.
'in' indicates a hidden word.
'ELITE' is hidden within 'caramel i tested'.
'the' acts as a link.
(Other definitions for elite that I've seen before include "Superior group in society" , "Group considered to have superior status" , "Chosen ones" , "Letter size; superior group" , "Superior or favoured group of people" .)
