Leftover chocolate ganache: need to refrigerate?

[yumyumyogi]

I have about half a cup of chocolate ganache left over from making macarons. Does it need to be refrigerated? I would like to save it for another use but don't want it to harden in the refrigerator.

I've frozen mine and defrosted it with no harm done to the ganache.

Oooh. Freezer. Good call. I assume it hardens? do you reheat it over the stove or microwave? Thanks, dolores!

You can reheat either way, just watch closely.
