Pumpkin Rataskep
Also known as: Ainu Pumpkin and Bean Mash, Kabocha Rataskep
Shiraoi Ainu pumpkin, bean and corn mixture seasoned with shikerpe and cod fat.

About Pumpkin Rataskep
This pumpkin rataskep follows the Shiraoi ceremonial version called Botubotu, also named Kampocha Rataskep. The Ainu cultural reconstruction manual combines pumpkin, beans and corn with shikerpe fruit.
Pumpkin and sugar bring sweetness, balanced by salt and the savoury richness of cod fat. Shikerpe, identified in the manual as kihada fruit, supplies the distinctive fruit seasoning.
The pumpkin is soft among the beans and corn. The mixture is substantial rather than soupy, with the cooking liquid reduced away in the documented preparation.
