Kashiwamochifu is a traditional Japanese confectionery crafted by Saison de Setsuko. This delicacy consists of a mochi, or rice cake, wrapped in a kashiwa (oak) leaf, which imparts a subtle earthy fragrance to the sweet. The mochi is typically filled with a smooth, sweetened red bean paste known as anko, offering a delightful combination of textures and flavors that reflect classic Japanese dessert traditions.
