Piece of camembert: ought it, typically, to be hard cheese? (5,5)

I believe the answer is:

tough titty

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

'be hard cheese?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'piece of camembert ought it typically' is the wordplay.
'piece of' indicates a hidden word.
'TOUGH TITTY' can be found hidden inside 'camembert ought it typically'.

'to' is the link.

Can you help me to learn more?
