Poke fun at barbecue offering (3)
I believe the answer is:
rib
I believe this is a double definition.
'poke fun' is the first definition.
(I've seen this in another clue)
'barbecue offering' is the second definition.
(I've seen this in another clue)
'at' is the link.
(Other definitions for rib that I've seen before include "knitting pattern" , "Kid" , "Tease good-naturedly" , "Curved bone joined to the spine" , "One of the 12 pairs of curved arches of bone" .)
