Hotteok is a variety of filled Korean pancake, and is a popular street food of Korea. The dough for hotteok is made from wheat flour, water, milk, sugar, and yeast. The dough is allowed to rise for several hours. Handful-sized balls of this stiff dough are filled with a sweet mixture, which may contain brown sugar, honey, chopped peanuts, and cinnamon. The filled dough is then placed on a greased griddle, and pressed flat into a large circle with a special tool with a stainless steel circle and wooden handle as it cooks.
In Korea, ready-made dry hotteok mix is commercially available in plastic packages. The mix also comes with a filling consisting of brown sugar and ground peanuts or sesame seeds.
