Mushrooms Tok Tang Sueay is a dessert that has evolved from Khao Tok Tang, an ancient Thai dessert with a sweet flavor, which is mainly made from coconut, coconut milk, and sugar. It is an ancient Thai dessert that is hard to find. It is also one of the provinces, one menus, honoring local food, "The Lost Taste" of Bangkok. Khao Tok Tang, which is about to disappear, has been evolved into 'Hed Tok Tang Sueay', which uses mushrooms, which are local agricultural products, and corn cobs left over
