Anger about new cooker (5)
I believe the answer is:
range
'cooker' is the definition.
(I know that cooker can be written as range)
'anger about new' is the wordplay.
'anger' becomes 'rage' (rage is a kind of anger).
'about' means one lot of letters goes inside another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'rage' placed around 'n' is 'RANGE'.
(Other definitions for range that I've seen before include "Shooting area - group of mountains" , "where cattle may graze" , "Wander freely" , "Scope; chain" , "Cooking stove or place for target practice" .)
