Carve portion of brisket, chewy (4)
I believe the answer is:
etch
'carve' is the definition.
(thesaurus)
'portion of brisket chewy' is the wordplay.
'portion of' says the answer is hidden in the clue.
'ETCH' can be found hidden inside 'brisket chewy'.
(Other definitions for etch that I've seen before include "What most engravers presumably find easy to do" , "Engrave (glass/metal)" , "Use acid to cut design" , "Cut using sharp instrument" , "Make designs" .)
