mouthwatering

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

'tasty' is the definition.
(something tasty or tempting is mouthwatering)

'chops wife devoured with group' is the wordplay.
'chops' becomes 'mouth' (I've seen this before).
'wife' becomes 'w'.
'devoured' becomes 'ate' (I've seen this before).
'with group' becomes 'ring' (I am not sure about the 'with' bit.).
'mouth'+'w'+'ate'+'ring'='MOUTHWATERING'

Can you help me to learn more?

(Another definition for mouthwatering that I've seen is " Very tempting".)

I've seen this clue in The Telegraph.
