I was wondering 2 things
Can you leave ganache at room temp and for how long?
If you refridgerate the ganache, can you heat it up in the microwave a little bit to soften it?
You can store in fridge and re-heat in microwave be careful not too over heat.
Do you mean on cake, on cake I am sure it will be fine for a couple of hours (2-3) but should be kept in fridge.
I don't have it on the cake yet, I am making 2 batches for a cake I am making tomorrow but won't eat until Saturday. One batch will be for filling and the other for coating the cake. I wanted to put it in the fridge until I need the filling one tomorrow and I will make the coating one fresh.
Once the cake is made is it ok to leave out until Saturday?
In collette peters' book she says it can be out on a cake for about two days. I've read that other places too. I've also read if you put a ganache covered cake in the fridge it will loose it's shine.
I have done ganache twice. The first time I put it in the frig just to see what it would do & it got the little condensation bubbles all over it.The next time I did it I left it out on the counter top covered. It was there several days & was fine. Ganache is soo good!!
