Rolls cut the wrong way (4)
I believe the answer is:
buns
'rolls' is the definition.
('bun' can be a synonym of 'roll')
'cut the wrong way' is the wordplay.
'cut' becomes 'snub' (synonyms).
'the wrong way' says the letters should be written in reverse.
'snub' written backwards gives 'BUNS'.
(Other definitions for buns that I've seen before include "Small rolls" , "Cakes" , "Food items" .)
