I made some chocolate ganache and I stored the left over in the fridge. How long does it last in the fridge? It has been about 2 weeks and I want to use it again. Any tips will be appreciated. Thank you.

Basically forever. Well, maybe not forever, but a lot longer than two weeks (it IS covered, right? - it might pick up smells from other food, otherwise). I'd say at least a couple of months.

A couple months in the fridge or the freezer?

Yea i have it stored in an airtight container. When I first did it I had to heat the whipping cream to melt the chocolate do I need to heat it again? Or just re-whip it?

A couple of months in the fridge. Of course, when you put it in the fridge, it gets pretty hard, so you either have to let it come to room temperature (that's what I prefer to do) or heat it a little in the microwave. But if you heat it, you run the risk of overheating it, and then you have to wait till it cools off and sets up again. I don't whip mine, so I don't know if you need to do it again once it's at room temp. It would probably last six months or more in the freezer.

Thank you. I'm going to use it tomorrow.

i store mine in airtight freezer bags. When I want to heat it up, you could just put the bag in a bowl of warm water-

I have had some for 2 months
