Trifle's quality resonating with us cooks (12)

I believe the answer is:
nugatoriness
'trifle's quality' is the definition.
The definition suggests a singular noun which matches the answer.
'resonating with us cooks' is the wordplay.
'with' means one lot of letters go next to another.
'cooks' indicates anagramming the letters.
'resonating'+'us'='resonatingus'
'resonatingus' with letters rearranged gives 'NUGATORINESS'.
