Joint holder (6)
(Another definition for meat-safe that I've seen is " food-store".)
This clue might be a double definition.
'joint' is the first definition.
(thesaurus)
'holder' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for skewer that I've seen before include "Kebab-securer" , "Pin holding the roast together" , "The heart of kebab" , "Meat-securing pin" , "Metal pin for meat" .)
