Article Cameron edited, consuming one kind of coffee (9)
I believe the answer is:
americano
'kind of coffee' is the definition.
'article cameron edited consuming one' is the wordplay.
'article' becomes 'a' (indefinite article).
'edited' indicates an anagram.
'consuming' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'a'+'cameron'='acameron'
'acameron' is an anagram of 'amercano'.
'amercano' enclosing 'i' is 'AMERICANO'.
(Other definitions for americano that I've seen before include "drink" , "Style of coffee" , "Espresso diluted with hot water" .)
