Can white chocolate be refrigerated or frozen?
White chocolate can be refrigerated. You need to ensure that it is stored in a place that has cool temperatures between 65F and 70F. You can get some details about its storage from http://www.tifachocolate.com/about-chocolate/storing.php.
no but it will be hard
Yes; if you want it to be cold & you don't want it to melt. i personally think it's a lot better that way.
