Holding his dish and the pot (7)
I believe the answer is:
hashish
'the pot' is the definition.
(hashish is a kind of pot)
'holding his dish' is the wordplay.
'holding' indicates putting letters inside.
'dish' becomes 'hash' (hash is a kind of dish**).
'his' going into 'hash' is 'HASHISH'.
'and' is the link.
(Other definitions for hashish that I've seen before include "Pot" , "Resinous product of hemp smoked as drug" , "Dope" , "Grass" , "Hemp hallucinogen" .)
