“The term for cooked snails is called Shobu mai in Japanese and this is a popular food at Chinese festivals like Midwinter Festival or Spring Festival. It is usually served with white rice and kimchi. The reason it becomes a traditional dish that gets served at these events is because it was once considered the cheapest among all the dishes that could be prepared cheaply. This dish can be classified as steamed food and traditionally, rice cookers were not available back then so people had to use bamboo pots to prepare this dish instead of a microwave." - From Wikipedia https://en.wikipedia.org/wiki/Shobu_mai
