Pair carrying coffee tray (7)
I believe the answer is:
platter
'tray' is the definition.
(thesaurus)
'pair carrying coffee' is the wordplay.
'pair' becomes 'pr'.
'carrying' means one lot of letters goes inside another.
'coffee' becomes 'latte' (I've seen this before).
'pr' enclosing 'latte' is 'PLATTER'.
(Other definitions for platter that I've seen before include "main course" , "old record?" , "Large flat serving dish" , "Charger" , "Salver" .)
