Ambassador is partial to caramel cheesecake (6)

I believe the answer is:

elchee

'ambassador' is the definition.
(I've seen this before)

'partial to caramel cheesecake' is the wordplay.
'partial to' indicates a hidden word (the answer forms part of the clue).
'ELCHEE' is hidden in the letters of 'caramel cheesecake'.

'is' is the link.

(Another definition for elchee that I've seen is " Ambassador".)

I've seen this clue in The Guardian.
