After applying a very thin coating of whipped cream it’s time for the marzipan. The traditional color is green but you can find all sorts of variations such as the blue in the photos. Pink is quite common. For Halloween I’ve seen orange, red at Christmas, and yellow at Easter. The trick is to get the marzipan in an even, thin layer. They have a mechanized roller to get it perfect at the bakery. I don’t know if a pasta machine would work well for a home cook otherwise you would need some splendid hand-rolling capabilities.
