Composer taking against empty gorge (7)
I believe the answer is:
satiate
'gorge' is the definition.
(I know that gorge can be written as satiate)
'composer taking against empty' is the wordplay.
'composer' becomes 'satie' (French composer Erik Satie).
'taking' indicates putting letters inside.
'empty' suggests removing the centre.
'against' with its centre taken out is 'at'.
'satie' going around 'at' is 'SATIATE'.
(Other definitions for satiate that I've seen before include "Satisfy fully, cloy with excess" , "Completely satisfy" , "Gratify fully" , "Overfill - gorge" , "gladden a gourmand" .)
