Stirring cauldron, cut a sinister figure (5,7)

I believe the answer is:

count dracula

I'm a little stuck... Click here to teach me more about this clue!

'sinister figure' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'stirring cauldron cut a' is the wordplay.
'stirring' indicates an anagram.
'cauldron'+'cut'='cauldroncut'
'cauldroncut' with letters rearranged gives 'countdracul'.
'countdracul'+'a'='COUNT DRACULA'

Can you help me to learn more?

(Another definition for count dracula that I've seen is " Bram Stoker's vampire".)

I've seen this clue in The Independent.
