Meat product, cold joint AA lot prepared (9)

I believe the answer is:

chipolata

I'm a little stuck... Click here to teach me more about this clue!

'meat product' is the definition.
The definition suggests a singular noun which matches the answer.

'cold joint aa lot prepared' is the wordplay.
'cold' becomes 'c' (eg on taps).
'joint' becomes 'hip' (part of body).
'prepared' indicates an anagram.
'aa'+'lot'='aalot'
'aalot' is an anagram of 'olata'.
'c'+'hip'+'olata'='CHIPOLATA'

Can you help me to learn more?

(Other definitions for chipolata that I've seen before include "Type of sausage" , "Small thin sausage" , "Party snack" , "banger" .)

I've seen this clue in The Sun.
