Dave's press officer screens something hot and steamy (8)
I believe the answer is:
espresso
'something hot and steamy' is the definition.
'dave's press officer screens' is the wordplay.
'screens' indicates a hidden word.
'ESPRESSO' can be found hidden inside 'daves press officer'.
(Other definitions for espresso that I've seen before include "that's stimulating" , "Coffee-making machine" , "Coffee made by forcing steam through grounds" , "Strong coffee made with steam machine" , "Italian strong coffee traditionally in a little cup" .)
