There are many kinds of delicious food or snacks sold in winter. I like most of them specially ho-tteok and tteokpokki.
Another delicious snacks during the winter season is Beungeoppang. Bungeo is a type of fish and ppang means bread. It is sold by open-air food vendors throughout Korea.
Beungeoppang is a fish-shaped korean pastry but doesn't contain any fish. It has red bean paste inside and the outside part that covered the bean paste tastes like waffle. It is delicious when it served hot.
Beungeoppang is also sold with eomug.
