Sort of barbecue — mostly for young carnivore (4,3)
I believe the answer is:
bear cub
'for young carnivore' is the definition.
(bear cub is a kind of young carnivore)
'sort of barbecue mostly' is the wordplay.
'sort of' indicates anagramming the letters.
'mostly' means to remove the last letter.
'barbecue' with its final letter taken off is 'barbecu'.
'barbecu' is an anagram of 'BEAR CUB'.
(Other definitions for bear cub that I've seen before include "Paddington, perhaps" , "youngster?" , "Young carnivore" , "Ursine baby" .)
