Sweet twice as good in France? (6)

I believe the answer is:

bonbon

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

'sweet' is the definition.
(I know that bonbon is a type of sweet)

'twice as good in france?' is the wordplay.
'twice as' becomes 'bon' (I can't justify this - if you can you should give a lot more credence to this answer).
'good in france?' becomes 'bon' (French for 'good').
'bon'+'bon'='BONBON'

Can you help me to learn more?

(Other definitions for bonbon that I've seen before include "a tasty sweet - in France" , "French sweet" , "Confection" , "Candy, doubly good in France?" , "Sweetie" .)
