Does anyone have any tips for doing this? Obviously a turn-table and scraper works for a basic round cake, but what about other ones? What about, say, a rollercoaster-shape carved into a cake? (What I'm about to do.)
Are you talking about what tool to use? If so, I went to the dollar store and bought those really thin plastic food cutting mats. Just cut a piece out, the size you like, and you have a flexible bench scraper.
I just used it on a 3d cake to apply ganache and it worked perfectly.
That's what I thought I should do, just wondered if there were any awesome tips people had. Thanks.
I use a pastry bag fitted with a coupler and no tip. I pipe in a thin zig-zag motion to get the icing on then use a spatula to smooth the icing. This way the icing is on the sides without getting all the crumbs mixed in and it is easier for me to smooth it out. I find it much faster as well.
