Tray emptied to hold rum drink (5)
I believe the answer is:
toddy
'drink' is the definition.
(toddy is a type of drink)
'tray emptied to hold rum' is the wordplay.
'emptied' means to remove the middle letters.
'to hold' means one lot of letters goes inside another.
'rum' becomes 'odd' (rum can mean strange or dubious).
'tray' with its middle removed is 'ty'.
'ty' placed around 'odd' is 'TODDY'.
(Other definitions for toddy that I've seen before include "Hot liquor" , "Mixture of spirits, sugar and hot water" , "Hot drink made with rum or whisky" , "Hot spirituous drink" , "A hot tipple" .)
