From the existing encyclopedia
Home cooks and herbal tea drinkers know Yellow Dock for its signature scent and the way it layers with citrus, honey, or allium. Cross-link pantry planning with v1 kits on the store page when this item appears in a bundle. Complements lemon, lime, or vinegar acidity in dressings and marinades. When substituting dried Yellow Dock for fresh, use about one-third the volume and bloom in fat or hot water before adding acid or dairy.
