Vessel containing some cooked chowder (4)
I believe the answer is:
dhow
'vessel' is the definition.
(dhow is a kind of vessel)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dhow that I've seen before include "Arab sailing boat" , "Arab coastal vessel" , "Arab vessel with lateen sail" , "Arabian ship" , "Arab lateen-rigged sailing ship" .)
