Gyeran ppang

Gyeran-ppang is a South Korean street food. It is a fluffy, oblong-shaped piece of bread that is sweet and savory with a whole egg inside the pancake dough. A gyeran-ppang machine is an appliance with a few dozen oblong slots for pouring cake batter and eggs. The cake mix usually consists of wheat flour, baking powder, milk, eggs, butter, sugar, salt and vanilla extract. A whole egg is cracked onto the batter in each slot, and the egg breads are cooked till golden brown. Common toppings include chopped parsley, cheese, and diced ham.
