Pasta originally celebrated in a form of verse (9)

I believe the answer is:

macaronic

'a form of verse' is the definition.
(verse containing phrases from multiple languages)

'pasta originally celebrated' is the wordplay.
'pasta' becomes 'macaroni' (macaroni is a kind of pasta).
'originally' suggests taking the first letters.
The initial letter of 'celebrated' is 'c'.
'macaroni'+'c'='MACARONIC'

'in' is the link.

I've seen this clue in The Guardian.
