Cheese whiff rising, about caught too much! (7)
I believe the answer is:
ricotta
'cheese' is the definition.
(ricotta is a kind of cheese)
'whiff rising about caught too much' is the wordplay.
'whiff rising about' becomes 'rica' (I can't justify this - if you can you should believe this answer much more).
'caught' means one lot of letters goes inside another.
'too much' becomes 'ott' (short for 'over the top' - informal British).
'rica' going around 'ott' is 'RICOTTA'.
Can you help me to learn more?
(Other definitions for ricotta that I've seen before include "cheese found" , "Italian 8 across" , "One soft cheese" , "Read the riot act about the cheese" , "cheese, Italian style" .)
