Spits in empty stonework jugs (7)
I believe the answer is:
skewers
'spits' is the definition.
(I know this)
'empty stonework jugs' is the wordplay.
'empty' says to hollow out the word (remove centre letters).
'jugs' becomes 'ewers' (ewer is a type of jug).
'stonework' with its middle taken out is 'sk'.
'sk'+'ewers'='SKEWERS'
'in' acts as a link.
(Other definitions for skewers that I've seen before include "pins for cooking" , "Sticks" , "They make bent" , "Impales" , "Long pins for holding meat" .)
