Cut from cashew nuts (4)
I believe the answer is:
hewn
'cut' is the definition.
(synonyms)
'from cashew nuts' is the wordplay.
'from' indicates the answer is hidden within the clue.
'HEWN' can be found hidden inside 'cashew nuts'.
(Other definitions for hewn that I've seen before include "Felled" , "Cut with blows" , "Cut with an axe or chisel" , "Shaped as with an axe" , "(Of wood) cut, chopped" .)
