Move Over, Kimchi: Tteokbokki is my Favorite Korean Food.
Tteokbokki is mainly considered to be a snack food in Korea, made from chewy rice cake, fish cake, and a sweet chili sauce. Additional ingredients are added depending on the chef - the dish above was almost exclusively rice cake and chili sauce, plus the hard-boiled egg. Most commonly, I see it with chunks of different kinds of meat (usually sausage) and vegetables (usually of the green variety).
The round rice cakes (usually made of flour these days) are chewy and relatively flavorless, but the bulk of the dish. The other solid ingredients add a bit of additional flavor and texture, but the best part is the sauce. It is usually very spicy, and what makes the dish special.
