I am just curious about how bakeries get those colored lines on a piece of cake. On a lot of miniature desserts they have little pink or green lines going up the side of the cake and it almost looks like its stenciled or transferred on. I have also seen chocolate with gold designs etched into it on pieces of cake. How can I achieve that type of effect on cakes I make at home? Usually the nicer bakeries have these types of designs on their pastries and cakes.
