Favourite of vegetarians in most of university (4)
I believe the answer is:
tofu
'favourite of vegetarians' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'in most of university' is the wordplay.
'in' says the answer is hidden in the clue.
'TOFU' can be found hidden inside 'most of university'.
Can you help me to learn more?
(Other definitions for tofu that I've seen before include "soybean curd" , "Vegetarian foodstuff made from soya beans" , "Substitute for meat" , "fare from Japan" , "food rich in protein" .)
