Dislike about university’s hint to suppress one crime? What’s cooking, seriously? (5,7)
I believe the answer is:
haute cuisine
'what's cooking seriously?' is the definition.
(high-level cooking)
'dislike about university's hint' is the wordplay.
'dislike' becomes 'hate' (to hate is to dislike strongly).
'about' means one lot of letters goes inside another.
'university' becomes 'U' (abbreviation for university).
'hint' becomes 'cuisine' (I can't explain this - if you can you should give a lot more credence to this answer).
'hate' enclosing 'u' is 'haute'.
'haute'+'cuisine'='HAUTE CUISINE'
'to suppress one crime?' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for haute cuisine that I've seen before include "Fine cooking" , "high table at the Sorbonne?" , "Menu" , "Cookery of a very high standard" .)
