Notes

  • Use prepared horseradish, not horseradish sauce. Look for prepared horseradish in the refrigerated section. Horseradish sauce is already mixed and won’t give the same clean, sharp flavor.
  • Start with less horseradish and adjust after chilling. Horseradish heat develops as it sits. Stir the sauce, chill it for at least 30 minutes, then taste and add more if needed.
  • Let it rest before serving. Even a short chill helps the flavors blend and mellow. Give it at least 30 minutes in the fridge for the best balance.
