Vessel raised at the dining table, perhaps (7)
I believe the answer is:
ketchup
'the dining table perhaps' is the definition.
I can't judge whether this defines the answer.
'vessel raised' is the wordplay.
'vessel' becomes 'ketch' (ketch is a kind of vessel).
'raised' becomes 'up' (similar in meaning).
'ketch'+'up'='KETCHUP'
'at' is the link.
Can you help me to learn more?
(Other definitions for ketchup that I've seen before include "Piquant sauce, often tomato based" , "Relish" , "Sauce made largely of tomatoes" , "Red sauce" , "Condiment" .)
