The fruits, usually used whole, have a pungent, anise flavour and aroma that comes from essential oils, mostly carvone and limonene. They are used as a spice in breads, especially rye bread which is denser because of the yeast killing properties of the essential oil, limonene.
Caraway is also used in liquors, casseroles, and other foods, especially in Central European and Scandinavian cuisine (sauerkraut for instance). It is also used to add flavour to cheeses such as havarti. Akvavit and several liqueurs are also made with caraway, and a tisane made from the seeds is used as a remedy for colic, loss of appetite and digestive disorders and to dispel worms.
