Excellent thing, tea or coffee perhaps? (3,5)
I believe the answer is:
hot stuff
I believe this is a double definition.
'excellent thing' is the first definition.
'tea or coffee perhaps?' is the second definition.
(Other definitions for hot stuff that I've seen before include "Very expert or attractive person" , "Such a talented person" , "Dish" , "Something sensational, daring or erotic" , "blue movie" .)
