Dessert is deformed when cooked (10)

I believe the answer is:

semifreddo

'dessert' is the definition.
(semifreddo matches up with the definition dessert)

'is deformed when cooked' is the wordplay.
'when cooked' indicates anagramming the letters.
'is'+'deformed'='isdeformed'
'isdeformed' is an anagram of 'SEMIFREDDO'.

I've seen this clue in The Telegraph.
