Impudence to criticise kitchen utensil (8)
I believe the answer is:
saucepan
'kitchen utensil' is the definition.
(I've seen this before)
'impudence to criticise' is the wordplay.
'impudence' becomes 'sauce' (I've seen this before).
'to criticise' becomes 'pan' (informal term meaning to criticise heavily).
'sauce'+'pan'='SAUCEPAN'
(Other definitions for saucepan that I've seen before include "Cooking utensil" , "kitchen item" , "Kitchen vessel" , "Kitchen utensil" , "pot-boiler?" .)
