From the existing encyclopedia
Home cooks and herbal tea drinkers know Horehound for its signature scent and the way it layers with citrus, honey, or allium. Introduce new ingredients gradually in cooking portions to learn flavor strength before scaling recipes. Complements lemon, lime, or vinegar acidity in dressings and marinades. When substituting dried Horehound for fresh, use about one-third the volume and bloom in fat or hot water before adding acid or dairy.
