Book one has expert on cheese (9)

Ross

I believe the answer is:

provolone

'cheese' is the definition.
(thesaurus)

'book one has expert' is the wordplay.
'book' becomes 'vol' (short for volume).
'has' is a charade indicator (letters next to each other).
'expert' becomes 'pro' (short for professional).
'vol'+'one'='volone'
'volone' after 'pro' is 'PROVOLONE'.

'on' is the link.

I've seen this clue in The Times.
