こってりみそ / Kotteri Miso / Ramen Gojōgen - Sapporo, Hokkaido
Soup is made from 100% pork bones, miso tare and pork back fat. Noodles ordered via Satō Seimen Kōjō, based out of Asahikawa. Originally opened by master Azuma-san, now run by his son. The two of them working together created the paitan style soup currently being served. The recipe uses both pork bones and trotters, boiled twice and washed, then boiled again for 25 hours. Two branches in Hokkaido, flagship open until 3am. Since 1994.
