A beefy Russian? (10)
I believe the answer is:
stroganoff
'russian?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'a beefy' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stroganoff that I've seen before include "meat dish" , "Beef dish with mushrooms in sour cream" .)
