WHITE CHOCOLATE-CRANBERRY HOLIDAY BARK
Simply because of the volume, I makeshift a large double boiler from a saucepan and a large heat-resistant mixing bowl. Be careful -- the bowl gets hot. However, the recipe can easily be halved.
Bring water to a simmer over medium-low in a saucepan. Set a large heat-resistant bowl over the saucepan making sure water doesn't touch the bowl.
