Chillier setting for a new kitchen vessel (8)
I believe the answer is:
colander
'kitchen vessel' is the definition.
(I've seen this before)
'chillier setting for a new' is the wordplay.
'chillier' becomes 'colder' (I can't explain this - if you can you should give a lot more credence to this answer).
'setting for' is an insertion indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'a'+'n'='an'
'colder' enclosing 'an' is 'COLANDER'.
Can you help me to learn more?
(Other definitions for colander that I've seen before include "Straining pan" , "Container for straining water from food" , "Leaky vessel" , "Old crane (anag.)" , "It is used to strain water from food" .)
