Delicious drink, new crate sent round (6)
I believe the answer is:
nectar
'delicious drink' is the definition.
(I've seen this in another clue)
'new crate sent round' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'round' is an insertion indicator.
'crate' with letters rearranged gives 'ectar'.
'n' inserted inside 'ectar' is 'NECTAR'.
(Other definitions for nectar that I've seen before include "Drink of gods and insects" , "Sweet fluid produced by flowers" , "Sugary stuff in plants to attract insects" , "Sweet liquid of the gods" , "Divine drink" .)
