I have a wedding cake to do where the bride wants a rainbow cake style. She showed me a pic where all the colours are in stripes.
My question is, though I know how to do this sort of cake, how do I ensure that the colours come out nice and bright and also what about making sure the correct colour comes out!
My batter is usually a soft pale yellow just before I bake it. So my thoughts are that when I add say blue colouring, it might turn a shade of green because of the yellow colour to start with. Same with any other colour that may change when added to a pale yellow colour, like red going bit orangy etc.
Any advice appreciated.
