I'm a little stuck... Click here to teach me more about this clue!

'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" .)
