i'm new to cake decorating. In fact this site has given me the incentive to try , try.....i hope the qustion does not seem ridiculous...

1) If i have a whipped ganache filling in the cake......can it be on the shelf for a ay or two or does it have to be refrigerated.

2) For that matter other fillingd like puddings, whipping cream with strawberries, do all of them have to be in the fridge???

Here's a handy safe storage chart for frostings & fillings:
