Cook in oven or pan (5)
I believe the answer is:
roast
This clue is a double definition.
'cook in oven' is the first definition.
(I've seen this before)
'pan' is the second definition.
(both can mean to criticise)
'or' acts as a link.
(Other definitions for roast that I've seen before include "Traditional Sunday joint?" , "Heat strongly - criticise excessively" , "Be uncomfortably hot" , "Grill" , "Tear to pieces" .)
