I made a big batch of whipped ganache as a filling for 2 cakes that I was supposed to make this wknd. However there was a death in the family, and I'm not making the cakes anymore. Can I freeze the whipped ganache? How long will it keep in the fridge? I made it on Thursday and could use it for a cake I'm filling on Tuesday, will it be okay in the fridge til then. Regardless, it's still a lot of filling and won't be able to use it for that one cake I'm making.

Any advice? Tips?

Much appreciated
Susan
