Élite ate up scones etc. (5,3)
I believe the answer is:
cream tea
'scones etc' is the definition.
'elite ate up' is the wordplay.
'elite' becomes 'cream' (cream is a kind of elite).
'up' is an anagram indicator (letters get chucked up).
'ate' with letters rearranged gives 'tea'.
'cream'+'tea'='CREAM TEA'
(Other definitions for cream tea that I've seen before include "Light afternoon meal" , "tasty treat" , "Afternoon meal - macerate (anag)" , "calorie-packed meal" , "Meal with scones and jam" .)
