Do not leave cake unattended around vultures, jackals, or underpaid art students.

For perfect, easy-to-spread ganache, use slightly more (by weight) cream than chocolate. So if you have 1 1/2 pounds of chocolate, use about 1 3/4 pounds of cream. And make sure to allow for ample time for the ganache to set up.
