Dwelling on how suet is cooked (4,5)
I believe the answer is:
town house
'dwelling' is the definition.
(town house is a kind of dwelling)
'on how suet is cooked' is the wordplay.
'is cooked' indicates anagramming the letters.
'on'+'how'+'suet'='onhowsuet'
'onhowsuet' is an anagram of 'TOWN-HOUSE'.
(Other definitions for town house that I've seen before include "Fashionable urban dwelling" , "accommodation" .)
