Disclose forte in baking scones (7)
I believe the answer is:
confess
'disclose' is the definition.
(thesaurus)
'forte in baking scones' is the wordplay.
'forte' becomes 'f' (music abbreviation - loud).
'in' means one lot of letters goes inside another.
'baking' indicates anagramming the letters (letters baked or cooked into a new form).
'scones' anagrammed gives 'coness'.
'f' inserted within 'coness' is 'CONFESS'.
(Other definitions for confess that I've seen before include "Admit (to crime)" , "Tell a priest one's sins" , "Admit (to wrongdoing)" , "Plead guilty (in order to receive absolution?)" , "Concede" .)
