Cake-burner flared up (6)

I believe the answer is:

alfred

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

'cake-burner' is the definition.
I can't judge whether this defines the answer.

'flared up' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'flared' is an anagram of 'ALFRED'.

Can you help me to learn more?

(Other definitions for alfred that I've seen before include "Ninth century king of Wessex" , "- - Hitchcock" , "... the Great, 9th-century Anglo-Saxon king" , "A great king of Wessex, d. 899" , "Great English king" .)

I've seen this clue in The Irish Independent.
