Large dish of coffee in empty percolator (7)
I believe the answer is:
platter
'large dish' is the definition.
(I've seen this in another clue)
'coffee in empty percolator' is the wordplay.
'coffee' becomes 'latte' (type of coffee drink).
'in' indicates putting letters inside.
'empty' suggests removing the centre.
'percolator' with its centre removed is 'pr'.
'latte' placed within 'pr' is 'PLATTER'.
'of' acts as a link.
(Other definitions for platter that I've seen before include "Large shallow dish" , "Charger" , "old record?" , "Salver" , "main course" .)
