Cream in bagel: it enthrals (5)
I believe the answer is:
elite
'cream' is the definition.
(I've seen this before)
'in bagel it enthrals' is the wordplay.
'in' says the answer is hidden in the clue.
'ELITE' can be found hidden inside 'bagel it enthrals'.
(Other definitions for elite that I've seen before include "Creme de la creme" , "Chosen ones" , "Upper crust" , "Exclusive group" , "Privileged or posh group" .)
