Unwelcome gift made undrinkable coffee, hated from the start by girl (8,7)
I believe the answer is:
poisoned chalice
'unwelcome gift' is the definition.
(a poisoned chalice causes its recipient problems)
'undrinkable coffee hated from the start by girl' is the wordplay.
I cannot really understand how this works, but
'coffee' could be 'ice' (ice coffee is a kind of coffee) and 'ice' is present in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
This explanation may well be incorrect...
'made' is the link.
(Other definitions for poisoned chalice that I've seen before include "Source of trouble" , "undoing?" , "may be a curse in disguise" , "This is likely to cause trouble" , "that was the death of Gertrude" .)
