Dill weed is the leaf and stem of the dill plant. The seeds flavor is clean, pungent, and reminiscent of caraway, while dill weed (the leaf and stem) has a slightly mellower herb-like flavor. Although rare in cuisines that favor fennel, dill is commonly used in German and Scandinavian cooking. Dill weed is used in potato and pasta salads, dips, and to season fish.
