Notes

  • Never boil miso after adding it - this preserves its delicate flavor and nutrients
  • Start with less miso and adjust to taste
  • Use a strainer or ladle to dissolve miso smoothly into soup
  • Pair red miso with hearty dishes and white miso with lighter recipes
  • Add a splash of rice vinegar or citrus juice for brightness
  • Mix miso with butter or oil for an instant flavor upgrade to vegetables
