1. Is it necessary to refrigerate my black forest gateau?
Most cakes can be stored at room temperature for two days. When in doubt, always refrigerate. They last longer, especially if the weather is too humid or your kitchen gets too hot.
2. When frosting the black forest cake, how do you avoid it from crumbling?
Before frosting the black forest cake, make sure it has totally cooled. Freezing the cake layers before frosting is a great approach to avoid crumbling. Crumb coating, or frosting the black forest cake in a thin layer, captures crumbs and keeps it moist.
