Hakodate, a port city in Hokkaido, is considered the home of shio, or salt-based, ramen. The clear soup broth is made with chicken, pork, seafood, and kelp served with straight noodles cooked until tender. Although shio ramen is no saltier than shoyu ramen, it has a slightly different flavor profile to shoyu ramen with a cleaner, lighter taste that allows the chicken, pork, and seafood flavors to come through.
