Someone who prefers the best portion of strudel — it is tasty! (7)
I believe the answer is:
elitist
'someone who prefers the best' is the definition.
'elitist' can be an answer for 'someone' (elitist is a kind of someone). I am not sure about the remainder of the definition.
'portion of strudel it is tasty' is the wordplay.
'portion of' indicates the answer is hidden within the clue.
'ELITIST' can be found hidden inside 'strudel it is tasty'.
Can you help me to learn more?
(Other definitions for elitist that I've seen before include "arrogant" , "One without the common touch" , "No egalitarian" , "Favouring a chosen few" , "(One who is) discriminating in favour of select few" .)
