Food wrap can frustrate (7)
I believe the answer is:
tinfoil
'food wrap' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'can frustrate' is the wordplay.
'can' becomes 'tin' (synonyms).
'frustrate' becomes 'foil' (synonyms).
'tin'+'foil'='TINFOIL'
Can you help me to learn more?
(Other definitions for tinfoil that I've seen before include "Fine metal" , "A help in the kitchen" , "what can protect food" , "Thin metallic sheets for protecting food" , "Shiny food wrapping" .)
