Container of porridge (but does it clink?) (3)
I believe the answer is:
jug
'clink?' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for jug that I've seen before include "Large vessel with a narrow mouth" , "Pitcher" , "Where to keep milk" , "Stew or boil (rabbit)" , "Liquid container" .)
