Religious leader turns up at University, for a taste (5)
I believe the answer is:
umami
'for a taste' is the definition.
(I've seen this before)
'religious leader turns up at university' is the wordplay.
'religious leader' becomes 'imam' (an imam leads Muslims in prayer).
'turns up' shows that the letters should be reversed in order.
'at' says to put letters next to each other (I've seen this in other clues).
'university' becomes 'U' (abbreviation as in UMass).
'imam' in reverse letter order is 'mami'.
'mami' put after 'u' is 'UMAMI'.
(Other definitions for umami that I've seen before include "Savoury flavour" , "Savoury taste sensation produced by glutamates - I, a mum (anag)" , "Newly discovered taste" , "meaty taste" , "acquired taste perhaps" .)
