Broth families
Tonkotsu is pork bone simmered for hours until it turns milky and thick. Shoyu is a brown, soy-forward broth that often feels lighter. Shio is salt-based and clear, so the aroma and noodles lead. Miso is rounder and nutty, often with a warm finish. Chicken broths split into creamy paitan and clear chintan. Vegetable and mixed bases fit the Other field.
