Came on air stirring coffee (9)
I believe the answer is:
americano
'coffee' is the definition.
(type of coffee)
'came on air stirring' is the wordplay.
'stirring' indicates an anagram.
'came'+'on'+'air'='cameonair'
'cameonair' with letters rearranged gives 'AMERICANO'.
(Other definitions for americano that I've seen before include "drink" , "Style of coffee" , "Espresso diluted with hot water" .)
