A cheese list misplaced and not brought back (7)
I believe the answer is:
stilton
'a cheese' is the definition.
(stilton is a cheese)
'list misplaced and not brought back' is the wordplay.
'misplaced' indicates anagramming the letters (letters in the wrong places).
'and' means one lot of letters go next to another.
'brought back' says the letters should be written backwards.
'not' back-to-front is 'ton'.
'list' with letters rearranged gives 'stil'.
'stil'+'ton'='STILTON'
(Other definitions for stilton that I've seen before include "Cheese variety" , "Rich, blue-veined cheese" , "Strong Eng. cheese" , "Dairy product" , "Strong blue cheese" .)
