seen this several times but don't know what it means? does it mean to cut a layer of cake into two layers??? please and thanks.
Yes that is exactly what it means.
Yes! That's what it means ... , you had it right
Yes. And the purpose of torting is to fill in between the 2 layers with jam, pudding, icing, or whatever your choice, and you can also add fruit. It adds moisture and height to the cake, and IMHO it makes the cake more tasty. You may know this info already, but I'm saying it just in case
You can cut it with how much you want.
