So I am making a 1 tier topsy turvy cake...sounds simple enough as there isn't any stacking involved (although with the SPS its not nearly as nerve wracking as before)...I make 3 2-inch layers, 7-8-9. I level them as needed and followed the tutorial here on cakecentral. When I placed the largest layer(9in) on top it looked ok...as I begin the carve off the edges I notice its starting to lean...as I begin to think about crumb coating I can tell the bottom layer is literally collapsing under the weight of the 2 other layers. (I ended up taking off the top 2 - keeping the bottom layer to eat/dissect and just using the top 2 layers for the cake. The bottom layer was moist, fully cooked, dense...*perfect*)
Help me out here...where did I go wrong?
Typically, 4" is as high as you should go before adding internal support of some sort. 6" plus the combined stress of being tilty... not awesome. I don't think it was your recipe. Also try assembling your TT cake layers upside down, keeps the pressure off while you are manipulating.
I always knew the 4" rule - but in the tutorial he says nothing about providing support when using 3 layers....thanks for replying.
