Dairy product manufactured the wrong way (4)
I believe the answer is:
edam
'dairy product' is the definition.
(Edam is an example)
'manufactured the wrong way' is the wordplay.
'manufactured' becomes 'made' (I've seen this before).
'the wrong way' says the letters should be written in reverse.
'made' back-to-front is 'EDAM'.
(Other definitions for edam that I've seen before include "Made into a nice cheese" , "Red-coated cheese" , "Danish cheese" , "Type of cheese" , "Made into popular cheese" .)
