Pudding seems not to be cooked (4,4)

I believe the answer is:

eton mess

'pudding' is the definition.
(Eton mess is a dessert)

'seems not to be cooked' is the wordplay.
'to be cooked' indicates anagramming the letters (letters cooked into a new form).
'seems'+'not'='seemsnot'
'seemsnot' with letters rearranged gives 'ETON MESS'.

(Another definition for eton mess that I've seen is " Sweet".)

I've seen this clue in The Guardian.
