Raised edge of dish, say, turned over (6)
I believe the answer is:
flange
'raised edge' is the definition.
(I've seen this before)
'dish say turned over' is the wordplay.
'dish' becomes 'flan' (I've seen this before).
'say' becomes 'eg' (both can mean 'for example').
'turned over' says the letters should be written in reverse.
'eg' back-to-front is 'ge'.
'flan'+'ge'='FLANGE'
'of' acts as a link.
(Other definitions for flange that I've seen before include "Flat edge" , "Flat outer face of rolled-steel joist" , "Projecting rim or piece" , "Projecting (steel) collar" , "Raised edge of a wheel" .)
