I believe the answer is:

edam

I'm a little stuck... Click here to teach me more about this clue!

'a churn' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'it is made' is the wordplay.
'made' can be anagrammed to 'EDAM'.
Though, I am not clear how the anagram is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for edam that I've seen before include "something to have with crackers" , "Dairy product" , "milk product" , "Type of cheese" , "Cheese made in Holland" .)

I've seen this clue in The Globe and Mail.
