Beverages said to tantalise (4)
I believe the answer is:
teas
'beverages' is the definition.
(tea is a kind of beverage)
'said to tantalise' is the wordplay.
'said' indicates a 'sounds like' (homophone) clue.
'to tantalise' becomes 'tease' (teasing is a kind of tantalizing).
'tease' sounds like 'TEAS'.
(Other definitions for teas that I've seen before include "Afternoon meals" , "Hot drinks" , "Beverage made by steeping leaves in water" , "Beverages from leaves" .)
