Granny Smiths (6)
I believe the answer is:
apples
'granny smiths' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for apples that I've seen before include "Russets, pippins etc" , "They never fall far from the tree" , "Loud sharp cry" , "Divinely influenced" , "What you make cider from" .)
