The crust of snow skin mooncake is made of glutinous rice, which is frozen.[10] The snow skin mooncake is similar to mochi ice cream or yukimi daifuku, as both have glutinous rice crusts and have to be kept frozen.
Snow skin mooncakes are typically white and are served cold, which is why they are named "snow skin". However, mooncakes may have other colors because of added flavors in their crusts. For example, if chocolate is added, the color of the crust might be brown. Green-colored skin is made with the juice of the aromatic Pandan (Pandanus amaryllifolius) leaf, a popular and uniquely South-East Asian flavor.
While traditional mooncakes are usually filled with salted duck egg yolks and lotus seed paste or red bean paste, snow skin mooncakes can be filled with a variety of fillings such as mung bean paste, fruit, green tea, jam, strawberry, chocolate, coffee, cheese.[11] Other flavored fillings include durian, sesame, mango pomelo sago, and purple yam.
