AHello I've done topsy turvys before, but have a question. I'm looking to do one where the filling needs a dam. I've always filled before and then carved, but can't do that now since the dam would be lost. I would think I could just stack them dry, carve, and then seperate to do the dams and filling. Does that sound workable? Thanks Dave
AThe general recommendation is to NOT fill a TT--just stick layers together with BC. Besides not being able to carve it due to the damming necessary, fillings also create a more unstable cake.
I have done that several time with topsy turvy cakes with no problems. I did exactly what you described - stacked and carved without filling, then separated , dammed and filled. I did use thick lemon curd, and thick raspberry or chunky strawberry fillings (in thin layers) that were less likely to ooze, and made a sturdy dam material - thick ganache or stiff buttercream, depending on what blended with the final covering. Hope that helps!
