I believe the answer is:

estonia

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

'country' is the definition.
(European country)

I can't explain the remainder of the clue.

(Other definitions for estonia that I've seen before include "So eat in here in Eastern Europe" , "Republic in the Baltic region, once part of USSR" , "Land" , "So eat in poorly on the Baltic Sea" , "European country, capital Tallinn" .)

I've seen this clue in The Times.
