You got it my friend!
I was thinking to keep it under 30% though
Yes, I would think so too. My thinking was why take away the cake, when what we want to do is add frosting. But, I agree, I would reformulate to keep it at 30%. The question is always, what flavors do we want in a particular mix to predominate. The cake, the icing, or both? Not sure how I would adjust it until I had a chance to try a few variations. Depending on how strong the icing flavoring is, maybe something like this:
Yellow cake - 6%
Lemon - 8%
Icing - 5%
Cotton candy - 5%
Bavarian Cream - 3%
Sweet cream - 3%
That would keep the cake substantially in place and maybe give us enough room for the icing too. I do know that the lemon has to be higher percentage than the yellow cake. If I couldn't taste the icing, I would decrease both creams by 1% and increase icing by 2% and pray that it worked. If it didn't work, I would have to reduce the yellow and lemon again, while increasing the icing. We really want three predominant flavors here: lemon, yellow cake and icing. Only by playing around with it can we figure it out. With two predominant flavors, it's easy, adjust one or the other, or both. With three, hard to tell before mixing how to adjust....just get the beakers ready and hope you find it sooner rather than later. Doesn't take long to mix 100 drop flavorings at all. I can do an 800 drop test in under half an hour easily. That may be what this will require, and you guys have done it to me again with this icing thing. That's twice today! Glad I ordered the big bottle, lol!
