A member of the parsley family, caraway seeds (actually fruits of the Carum carvi herb) are quite aromatic and are most commonly used in European cooking (Germany, Austria and Hungary). The seeds are used in cakes, breads and even to flavor a liqueur called Kummel.
Caraway seed can be found in the spice section of most grocery stores. Whole Foods Market typically carries this spice in bulk as well as packaged. You can purchase this seed online at Target, Walmart and of course, Amazon.com: Organic Caraway Seed
