A turn in Cream or Foreigner (8)

I believe the answer is:
american
'foreigner' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'a turn in cream' is the wordplay.
'turn' is an anagram indicator.
'in'+'cream'='incream'
'incream' is an anagram of 'merican'.
'a'+'merican'='AMERICAN'
'or' is the link.
Can you help me to learn more?
(Other definitions for american that I've seen before include "US citizen seen in camera" , "from Hollywood?" , "One from the States" , "New York native" , "he's over the pond" .)
