Choice food's fragility (8)
I believe the answer is:
delicacy
I believe this is a double definition.
'choice food's' is the first definition.
(I've seen this before)
'fragility' is the second definition.
(I know that fragility can be written as delicacy)
(Other definitions for delicacy that I've seen before include "Choice item of food" , "Tasty titbit" , "Nice bit of food" , "expensive food" , "Tact - 9 or 13, for example" .)
