Drippy White (or colored) Ganache
This is the recipe I use to get the drippy effect on top of my cakes!
Put the candy melts in a shallow microwave safe bowl.
Add drops of the gel food color to the heavy cream if you're going to color the ganache.
Pour the cream over top of the melts and put the bowl into the microwave for 30 second intervals, stirring in between until the mixture is smooth. Use a whisk while the mixture is still warm to get rid of any pesky clumps.
