Yeah, I didn't know what it was either... so, if you're curious, mom and dad to be are NOT told the sex of their child at their ultrasound - that amazing info is entrusted to the baker :) The INSIDE color of the cake will be either pink or blue.... When they cut the cake, they find out which they are having, a boy or girl, along with the rest of the friends and family attending - in this case, blue! (I was secretly hoping there would be twins, a boy and a girl, as this was a two tiered cake) The bride requested black and white, but I threw in the pink and blue centers to the gumpaste flowers just to give some "cute factor". She also wanted question marks incorporated, so I tried to make them as formal as possible to blend in some with the scrolls. This was sour cream almond cake with cream cheese filling. Hand-piped, black scrollwork.
