Dill is a fragrant, feathery herb from the celery family, used in cooking for its fresh, slightly sweet, and tangy flavor, pairing exceptionally well with fish, potatoes, eggs, and cucumbers, especially in dishes like pickles, salads, and creamy sauces. Every part of the plant is edible, including the leaves (dill weed), seeds, stems, and flowers, with fresh leaves being best for bright flavor and seeds used whole or crushed for a stronger, caraway-like taste in breads, soups, and pickles.
