Cumin (/ˈkjuːmɪn/(Cuminum cyminum) is a flowering plant in the family Apiaceae, native from the east Mediterranean to South Asia.

Its seeds (each one contained within a fruit, which is dried) are used in the cuisines of many different cultures, in both whole and ground form. It also has many uses as a traditional medicinal plant.

Cumin is the dried seed of the herb Cuminum cyminum, a member of the parsley family. The cumin plant grows to 30–50 cm (12–20 in) tall and is harvested by hand. It is an annual herbaceous plant, with a slender, glabrous, branched stem that is 20–30 cm (8–12 in) tall and has a diameter of 3–5 cm ( 1 1⁄4–2 in). Each branch has two to three sub-branches. All the branches attain the same height; therefore, the plant has a uniform canopy. The stem is colored grey or dark green. The leaves are 5–10 cm (2–4 in) long, pinnate or bipinnate, with thread-like leaflets. The flowers are small, white or pink, and borne in umbels. Each umbel has five to seven umbellets. The fruit is a lateral fusiform or ovoid achene 4–5 mm ( 1⁄6– 1⁄5 in) long, containing two mericarps with a single seed. Cumin seeds have eight ridges with oil canals. They resemble caraway seeds, being oblong in shape, longitudinally ridged, and yellow-brown in colour, like other members of the Umbelliferae family such as caraway, parsley, and dill.

Originally cultivated in Iran and the Mediterranean region, cumin is mentioned in the Bible in both the Old Testament (Isaiah 28:27) and the New Testament (Matthew 23:23). The ancient Greeks kept cumin at the dining table in its own container (much as pepper is frequently kept today), and this practice continues in Morocco. Cumin was also used heavily in ancient Roman cuisine. In India, it has been used for millennia as a traditional ingredient in innumerable recipes, and forms the basis of many other spice blends.

The main producer and consumer of cumin is India. It produces 70% of the world supply and consumes 90% of that (which means that India consumes 63% of the world’s cumin). Other producers are Syria (7%), Iran (6%), and Turkey (6%). The remaining 11% comes from other countries. In total, around 300,000 tons of cumin per year are produced worldwide. In 2007, India produced around 175,000 tons of cumin on an area of about 410,000 ha., i.e. the average yield was 0.43 tons per hectare. The Maltese island of Comino is named for the plant that grows wild there.

Cumin seed is used as a spice for its distinctive flavour and aroma. Cumin can be found in some cheeses, such as Leyden cheese, and in some traditional breads from France. Cumin can be an ingredient in chili powder (often Tex-Mex or Mexican-style), and is found in achiote blends, adobos, sofrito, garam masala, curry powder, and bahaarat. In South Asian cooking, it is often combined with coriander seeds in a powdered mixture called dhana jeera.

Cumin can be used ground or as whole seeds. It helps to add an earthy and warming feeling to food, making it a staple in certain stews and soups, as well as spiced gravies such as curry and chili. It is also used as an ingredient in some pickles and pastries.

Cumin’s distinctive flavour is strong. It has a warm aroma due to its essential oil content. Its main constituent aroma compounds are cuminaldehyde (a promising agent against alpha-synuclein aggregation) and cuminic alcohol.
