Georgia new to each different cake filling (7)

I believe the answer is:

ganache

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

'cake filling' is the definition.
'ganache*' can be an answer for 'cake' (I've seen this before). I am not certain of the 'filling' bit.

'georgia new to each different' is the wordplay.
'georgia' becomes 'GA' (abbreviation for the US state).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'to' says to put letters next to each other.
'different' is an anagram indicator.
'each' is an anagram of 'ache'.
'ga'+'n'+'ache'='GANACHE'

Can you help me to learn more?

(Another definition for ganache that I've seen is " chocolate filling".)

I've seen this clue in The Daily Express.
