On camera I prepared a hot drink (9)
I believe the answer is:
americano
'a hot drink' is the definition.
(type of hot drink)
'on camera i prepared' is the wordplay.
'prepared' is an anagram indicator.
'on'+'camera'+'i'='oncamerai'
'oncamerai' with letters rearranged gives 'AMERICANO'.
(Other definitions for americano that I've seen before include "Espresso diluted with hot water" , "Style of coffee" , "drink" .)
