Hood organising cabal - hot stuff (9)
I believe the answer is:
balaclava
'hood' is the definition.
(I know that balaclava is a type of hood)
'organising cabal hot stuff' is the wordplay.
'organising' indicates an anagram.
'hot stuff' becomes 'lava' (I've seen this in another clue).
'cabal' with letters rearranged gives 'balac'.
'balac'+'lava'='BALACLAVA'
(Other definitions for balaclava that I've seen before include "Close-fitting woollen hood" , "Woollen helmet" , "Engagement" , "Where expensive charge was made" , "battle-site?" .)
