I have my first big wedding cake in a couple of weeks. I purchased the bakery craft separator plates and columns. Do I still put my cakes on a board? Or do they go directly on the plates? How do you transport these cakes? It will be a 4-tier cake and I'm just not sure if I should do any assembling ahead of time or not. My travel time is only about 10 min. to the venue.
Also, any advice on getting square corners perfect would be greatly appreciated.
I'm going to bump you because I want to hear the answers.
Sorry, can't help with the separator plates, but CC has a brilliant tutorial for square corners: http://www.cakecentral.com/article51-How-To-Frost-a-Square-Cake.html
You still need to use a cardboard circle the same size as your plate. The plate has a little spike sticking out of it, line your board up with the plate, and use the spike to poke a hole in the board.
We use the SPS on the wedding cakes we make where I work, and we always take them stacked. I would just use that rubber shelf liner to keep your cake from sliding in t he car.
