Make fun of upper class meat sauce (4)
I believe the answer is:
ragu
'meat sauce' is the definition.
'ragu' can be an answer for 'sauce' (Italian cooking sauce). I'm not sure about the 'meat' bit.
'make fun of upper class' is the wordplay.
'make fun of' becomes 'rag' (to rag on someone is to make fun of them).
'upper class' becomes 'u' (as in U- and non-U speech).
'rag'+'u'='RAGU'
Can you help me to learn more?
(Other definitions for ragu that I've seen before include "tomato and meat sauce" , "pasta sauce" .)
