Normal names manufactured cheese (8)
I believe the answer is:
parmesan
'cheese' is the definition.
(Parmesan is an example)
'normal names manufactured' is the wordplay.
'normal' becomes 'par'.
'manufactured' is an anagram indicator.
'names' is an anagram of 'mesan'.
'par'+'mesan'='PARMESAN'
(Other definitions for parmesan that I've seen before include "Pam earns this cheese" , "that's grated" , "Italian 8 across" , "Spearman (anag) - cheese" , "Cheese for grating" .)
