Uncovered buns cafe displayed, considered high-risk (6)
I believe the answer is:
unsafe
'displayed considered high-risk' is the definition.
I can't tell whether this defines the answer.
'uncovered buns cafe' is the wordplay.
'uncovered' says to take the centre.
'cafe' becomes 'safe' (I am not sure about this - if you are sure you should believe this answer much more).
The middle letters of 'buns' are 'un'.
'un'+'safe'='UNSAFE'
Can you help me to learn more?
(Other definitions for unsafe that I've seen before include "Precarious" , "Dangerous, insecure" , "Unreliable" , "Perilous" , "Dangerous - legally without basis" .)
