Use only the leaves of dill, and discard the thick stems. This herb is popular in Scandinavian and Eastern European cookery, and is added to soups, grilled and boiled fish, gravlax, potatoes and vinegars. In the USA, pickled cucumbers and gherkins are flavoured with dill; in India, it is used as a vegetable in regional dishes. It is combined with yoghurt and soured cream in Greece and Turkey, and with broad beans, rice and koftas in Iran.
