Rainbow Cake

I know, I know, rainbow cakes are ‘so yesterday’…

But truthfully, even at its rage, where every baker, every cake shops, and every blog was speckled with at least one ‘rainbow’ item. I wasn’t tempted at the very least to make one. Mostly because of the amount of work involved. And maybe because of the amount of food coloring that went into it.

Even now, as i sit typing this, the one slice of cake that i cut for the photos remain untouched.

So why make rainbow cake you ask?

Well you see, a close relative of mine has just opened up a cafe. She wanted rainbow cake on the menu and I was to experiment with a few recipes and decorating options.

The cake had to be pretty enough to sit on her display chiller. So I decided to pipe rainbow roses around and on the cake.

It’s a lot of work, a lot of piping bags, and a lot of bowls. But i came up with a good solution on how to minimize them. First, I tinted a good amount of buttercream YELLOW. I took my first pipping bag, and piped yellow roses on where it should be. Then i divided ALL yellow buttercream into two. Onto one bowl of my yellow buttercream, and added a few drops of red to make ORANGE. In a way, you can say that i am recycling my yellow buttercream to make orange. And when i am done with my orange roses, i added even more red coloring to make my RED buttercream.

To the second batch of yellow butter, I added drops of blue to make GREEN buttercream. Leftover green buttercream were added with more blue coloring to make BLUE buttercream. And when i am done, I took leftover RED buttercream, mix with BLUE buttercream and my final color, which is PURPLE buttercream.
Which pretty much means that instead of ending up with all 6 colors of buttercream, I was left with only leftover purple buttercream.

Geez, I hope i dont confuse you.

Whatever the case, I hope my relative’s pastry chef has the patience of a Saint. Because if making this rainbow cake daily was one of the job descriptions, I would tender my resignation.
