Share a little about the materials, processes, and techniques used to create this cake Shells are made from melting white chocolate, then mixing in a dab of peanut butter candy and and a dab of orange candy, swirling it and then pouring into different shell molds. By mixing the colors it gives the shells a real look. The sand is raw sugar. The coral is made from taking grape vines, letting them dry out for a couple of days then dipping them into the melted white chocolate. I would let them dry then dip then again and dry, continue this until you get the look you are wanting.
