I haven't used a lot of fillings, but when I do, I always use a BC damn. But this time I am crumb coating with ganache so have no BC. Do I really need a damn for the Costco choc mousse filling? Costco doesn't seem to use one.....
I've never used Costco fillings, but if you feel that it may require a dam, you can use the ganache to create the dam. It doesn't have to be buttercream.
Thanks! Just realized that I used the wrong "dam"...
well darling let me tell ya this.. anytime I am torting and filling a cake I use alot of damn's and a BC dam too. You feel free to use both too. (that made me smile, thanks)
typically, when filling use a dam about 1/4' from the edge, put some weight on top or let it settle overnight. then remove excess from the sides wherever it has oozed out.
But since you are using ganache I would suggest maybe ending the filling about 1' from the edge of the cake, and let it settle over night. That should give it plenty of room to expand out without causing too much overflow onto your cake.
Thanks Tesso I needed a laugh today.
