I'm so confused. I've read ganache is only safe for up to 4 hours out of the fridge, and then I've read in other places it is safe for up to 2 days out of the fridge (room temperature). Does anyone know for sure what it's room temp shelf life is?
Hi, I have used ganache as a filling and the shelf life would be 2-3days.
What about in the freezer? how long will it last?
Is there a difference in the shelf life if it's a filling versus the cake being covered in it? I'm covering a cake in white chocolate ganache for a wedding and wonder if it will be safe to leave out for more than 6-8 hours.
I don't think the shelf like changes on filling vs. covering I've had a cake out for 8 hrs. with a ganache icing and it did fine and still tasted great.
The shelf live is gonna depend on the ratio of cream to chocolate...the higher the ratio of cream to chocolate the shorter the shelf life (at room temp).
A really hard ganache such as a ratio of 2 parts chocolate to 1 part cream is similar in consistency to a chocolate truffle candy. This is the kind of ganache that can be out in room temp for a few days. It's basically like milk chocolate. If you're using a softer ganache such as 1:1 ratio than that really shouldn't be out at room temp for more than 3-5 hours. A whipped ganache filling should never be out at room temperature. This is my understanding. If you're refrigerating the ganache the shelf life is the same as the shelf life of heavy cream, you can freeze ganache to extend the life, I do it all the time.
