Sauce turned up with gold rice dish (5)
I believe the answer is:
pilau
'rice dish' is the definition.
(I've seen this before)
'sauce turned up with gold' is the wordplay.
'sauce' becomes 'lip' (both can mean insolence).
'turned up' says the letters should be written backwards.
'with' says to put letters next to each other.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'lip' reversed gives 'pil'.
'pil'+'au'='PILAU'
(Other definitions for pilau that I've seen before include "Eastern dish" , "Rice seasoned with spices and cooked with meat or vegetables" , "Indian dish of rice boiled with meat, vegetables, spices etc" , "Speciality" , "Type of rice" .)
