Today is my first time making ganache. I'm going to dip the top of cupcakes in it. Once it's on the cupcakes, do they need to be refrigerated or can they sit out?

ganache is more sensitive than regular icing. If you're going to eat them in a day or two, they can sit out just fine. Any more than that, and I'd refrigerate them.

I let my regular icing sit out for days and days ... I never referigerate it.

Tried that with some leftover ganache and had to throw the "warm and now all fuzzy" container away! Learned my lesson on THAT one!

Thank You!

They can sit out. The cupcakes woould mold before he ganache.

I covered a cheesecake the other day and refrigerated it. Took it out a little while before cutting and it was fine. So I guess either way is ok.

Thank you everybody. I do have one more question. I plan on using the leftover ganache to make truffles. How long will the leftover ganache keep in the refrigerator? And once I make the truffles, can they sit out at room temp since the ganache is sealed inside the chocolate?

I AM NOT SURE BUT i HAVE A BOWL IN THE CUPBOARD THATS BEEN THEIR FOR 2 MONTHS i FORGOT ABOUT IT, AND IT LOOKS FINE....

If you were topping cuppies with it i would keep them out a few days but after that your cupcake would be stale anyway.

If you made the ganache in a sterile environment it will last for about two weeks in the fridge, possibly longer depending on your cream. But you need to remember it is still cream so it needs to be treated accordingly.
