A snake, I see, can be something to savour (5)
I believe the answer is:
aspic
'be something to savour' is the definition.
I can't tell whether this definition defines the answer.
'a snake i see' is the wordplay.
'a snake' becomes 'asp' (asp is a kind of snake).
'see' becomes 'C' (the word for the letter, according to Chambers).
'asp'+'i'+'c'='ASPIC'
'can' acts as a link.
Can you help me to learn more?
(Other definitions for aspic that I've seen before include "Savoury jelly for coating meats and eggs" , "Savoury jelly for meat or vegetable" , "Ending of Marlowe's thriller" , "Glaze" , "that's clear?" .)
