Best stuff outside Spain (5)
I believe the answer is:
cream
'best' is the definition.
(both can mean the elite)
'stuff outside spain' is the wordplay.
'stuff' becomes 'cram' (cramming is a kind of stuffing).
'outside' indicates putting letters inside (some letters go outside others).
'spain' becomes 'e' (abbreviation for Espana).
'cram' going around 'e' is 'CREAM'.
(Other definitions for cream that I've seen before include "Best - ointment" , "Milk product" , "Top of milk or society" , "It rises to the top, the best" , "Thick milk" .)
