Making ramen soup at home is a fun, customizable cooking project. Our shoyu ramen recipe comes from Rai Rai Ken, a restaurant in Manhattan's East Village, and starts with with their kitchen's rich, complex soup base. For shoyu or soy sauce ramen, we add soy sauce, sake, and mirin to make the well-seasoned broth. Thin ramen noodles are cooked separately and added to each bowl before the broth is poured in. Serve with your choice of toppings, such as hard-boiled egg, cooked spinach, chopped scallions, nori, and bamboo shoots.
