Try some nougat, tempting (7)
I believe the answer is:
attempt
'try' is the definition.
('attempt' can be a synonym of 'try')
'some nougat tempting' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ATTEMPT' can be found hidden inside 'nougat tempting'.
(Other definitions for attempt that I've seen before include "Effort; go" , "Shot" , "Try, make an effort" , "Endeavor, try" , "Undertake" .)
