Hobaktteok

Hobak-tteok is a variety of siru-tteok (steamed rice cake) made by mixing fresh or dried pumpkin with glutinous or non-glutinous rice flour, then steaming the mixture in a siru (rice cake steamer). Washed pumpkin, preferably Korean cheese pumpkin called cheongdung-hobak (청둥호박), is minced after having its seeds removed by scraping. It is then mixed with rice flour and (optionally) sugar, and then sieved. Hobak-goji (julienned and dried pumpkin pieces) may replace the minced fresh pumpkin, in which case the flour is sieved before the addition of pumpkin pieces. Chestnuts, jujubes, red beans, and/or black beans may also be added to the sieved flour mixture. Finally, it is steamed in siru (steamer).
