Made aunt go off chewy sweet (6)
I believe the answer is:
nougat
'chewy sweet' is the definition.
(I've seen this before)
'made aunt go' is the wordplay.
'made' indicates an anagram.
'aunt'+'go'='auntgo'
'auntgo' with letters rearranged gives 'NOUGAT'.
'off' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for nougat that I've seen before include "Chewy confection with nuts, cherries" , "Chewy confection with nuts, fruit, etc" , "Type of confection" , "Chewy nutty sweet" , "Sweet made from honey, egg white and nuts" .)
