The layers function as a wrapper and box. A soft inner skin is made from tiny particles of food, mixed with either algae extract or chitosan (a biochemical polymer), and held together with calcium or magnesium ions. For extra protection, a firm outer skin made from a sugar derivative can be added, and then eaten or peeled off. (It’s biodegradable.) The concept allows for imaginative gastronomy—adding crunchy nuts or grains to the exterior or pairing it with something complementary, such as a coconut skin with mango or strawberry ice cream (left).
