What is cumin? | Seed of flavor and health

If you are not familiar with using spices in your food and want to learn, the journey will take you around the globe and through time, from ancient to modern, even if it is just a little seed, like cumin. 

If you ask someone from India or Pakistan what cumin is, the short answer is that it is a spice essential to cooking in the region, a tiny storehouse of flavor and health, with hardly any recipe that is complete without it. But if you want more information about cumin so you can incorporate it into your cooking or benefit from its healing properties, you will find things not so simple—these little spice seeds have a world all their own.

What is cumin and what is not

Knowing different types of cumin and how to use them can be confusing. In everyday language, the word jeera or zeera refers to cumin in the Indian subcontinent. There is the safed zeera, or ‘white cumin’, and kala/shahi zeera, or black/royal cumin. Each type is used differently because it has distinct flavor and health benefits, but it is tricky to recognize and distinguish the two types of this little seed, each full of flavor and medicinal value. 

White cumin (standard) is known by the botanical name Cuminum cyminum—a flowering plant in the Apiaceae (parsley) family. The plant is native to India, Turkey, and the eastern Mediterranean. Black or royal cumin is known by the botanical name Bunium persicum (synonymous with Elwendia persica)—also in the Apiaceae family. It is native to India, Pakistan, China, Afghanistan, Persia, Central Asia, and Egypt.  

Now comes the tricky part—many seeds are labelled black cumin but are completely different. Confusion arises from botanical misclassifications, similar appearances, and overlapping usage of vernacular or common names. 

Black cumin vs Nigella seeds

Kalonji, or Nigella seed from the plant Nigella sativa, is often mislabeled—but black seed is not black cumin. It doesn’t belong to the Apiaceae family; instead, it comes from the Ranunculaceae (buttercup) family. Nigella sativa is a small shrub that produces white, pale purple, or pale blue flowers. It grows worldwide but is most frequently found in southern and eastern Europe, the Middle East, North Africa, and southwest Asia. 

Great pignut seeds are not black cumin

Seeds of another plant, botanically known as Bunium bulbocastanum L. and commonly known as the great pignut, are also confused with black cumin. This plant belongs to the same genus, Bunium, and the same family, Apiaceae, as Bunium persicum (black cumin). But it is a different species native to western and southern Europe. 

Kalijiri vs black cumin

Seeds of yet another plant, Veronica anthelmintica, are also mislabeled as black cumin. However, this plant belongs to the Asteraceae, or daisy family, and is native to parts of Africa and Asia. The visual similarity and the seeds’ Indian name, ‘kalijiri’, contribute to its mislabeling, despite no relation to black cumin.  

Persian cumin vs black cumin

Caraway seeds are also often confused with black cumin. Both come from the same family, Apiaceae, but from different plants. The plant that produces caraway seeds is botanically known as Carum carvi and is native to Europe, North Africa, and parts of West and Central Asia with a temperate climate. The visual similarity of the seeds and their vernacular names, like Persian cumin and siah zeera, are the primary causes of the confusion. 

White vs black cumin: Flavor and aroma

So, basically, there are only two types of cumin: white (Cuminum cyminum) and black (Bunium persicum). Both are commonly used in the Indian subcontinent for cooking and traditional medicine. 

The flowers of Cuminum cyminum, or the white cumin plant, are small, delicate, and pink or white. The flowers of Bunium persicum, or black cumin, are similar—small and pure white or white with a faint hint of pink. One plant may have several flowers, which produce small seeds. Technically, cumin seeds are the dried fruits of these plants. They develop from the plant’s small flowers into white or black dried fruits that tightly enclose a single seed. 

Standard or white cumin has a strong flavor and aroma. It’s savory, nutty, and slightly bitter on its own, but when fried, it tastes earthy, releases a warm aroma, and defines the overall flavor profile of a dish. These seeds are light grey or yellowish-brown, and oblong and fuller in shape. 

Black cumin is thinner, darker, and more curved. Its flavor is more complex but milder, with a hint of sweetness—earthy, slightly bitter, and pine-like. Its aroma is finer, sweeter, and woodier. Unlike white cumin, its taste and aroma don’t hit instantly, but linger and grow. So while you can be generous with white cumin, only a little of black does the trick.  

Black cumin (Bunium persicum) grows much more slowly than the white type and is harvested in smaller quantities. Its rarity and nuanced flavor and aroma made it a spice reserved for royal and festive dishes in Moghul kitchens—leading to the name shahi, or royal cumin.  

If you want to use these two types of cumin, make sure you buy the right seeds. When you are preparing a dish with this spice, it can make a huge difference if you accidentally use one that’s labeled incorrectly.  

Origin of cumin—a long journey from the ancient past

Archeological findings reveal that cumin (Cuminum cyminum) has been used and cultivated since ancient times. Excavations at the Altit Yam site traced wild cumin seeds back to the 6th millennium BCE. The earliest reference to cumin indicates it was used as an ingredient in the mummification of pharaohs’ bodies—dating back about 5,000 years. Excavations in Syria found seeds dating back to the 2nd millennium BCE. While the precise origins of cumin are debated, it was most probably native to parts of the eastern Mediterranean and today’s West Asia. 

The world’s earliest recipes, written on clay tablets found in Mesopotamia, mention cumin. The Egyptians valued it beyond mummification—they used it in rituals, food, medicine, and perfumery. Middle East and North Africa also adopted it in dishes and spice blends. In the Indian subcontinent, the spice was essential to local food and a valuable part of Ayurvedic healing. Greeks and Romans also used it in food and to prepare remedies. In the Middle Ages, Europeans believed cumin improved fidelity and bonds of love—they would put the seeds in the pockets or socks of their loved ones travelling away from home to keep them faithful. When Spanish and Portuguese settlers took it to Mexico, it became a quintessential part of Mexican food. 

Cumin is not only one of the oldest cultivated plants, but it also traveled great distances around the globe and became part of local culture and cuisine worldwide. 

Unlike Cuminum cyminum (white cumin), Bunium persicum (black cumin) was not cultivated in ancient times. It was undoubtedly an integral part of traditional medicine systems, such as Persian and Ayurvedic. It was also one of the ingredients that travelled along the ancient Silk Road. Yet people did not cultivate it. They foraged and harvested it from the wild in the plant’s natural habitat. This plant is difficult to domesticate; both seed germination and maturity take a long time. Even now, commercial cultivation is rare and mostly experimental; the supply line mainly relies on wild-harvested seeds.

How cooking in the Indian subcontinent uses cumin spice

Today, India is the largest exporter of cumin seeds. The Indian subcontinent is also very much associated with the spice. The growing popularity of iconic dishes from the region has also brought the spices that contribute to their flavors into global focus. People worldwide are incorporating these spices into their food for flavor and health benefits. Cumin is a big part of the cuisine in the Indian subcontinent, particularly North India and Pakistan, because it is a foundational spice. The Hindi word jeera or the Urdu zeera is often used internationally instead of cumin. 

Here are the most common ways it is used in the Indian subcontinent’s cuisine: 

• Whole seeds are fried in oil or ghee with ginger-garlic paste, onion, and other spices to build a base before adding the main ingredients. This method is most commonly used when preparing curries, lentils, vegetables, and rice dishes. Depending on the dish, ground cumin also adds richness and flavor to the base—it blends well into sauces. 
• Cumin seeds are also fried as tadka (tempering)—meaning they are fried and added to prepared food as the final touch that completes the dish. This method is most frequently used to prepare dishes such as dal (lentils). 
• Whole seeds are dry-roasted in a hot pan (without adding water, ghee, or oil) until they release their aroma. When cooled, the seeds are ground to use as a flavor enhancer in condiments such as traditional raita (Indian yogurt with fresh tomatoes, onions, and roasted eggplant, etc., seasoned with spices). Whole dry-roasted seeds also add a burst of flavor and aroma when sprinkled on salads. They are an integral part of the famous Indian spice blend, garam masala. Chaat masala, another popular spice blend in the Indian subcontinent, also includes cumin. The world-famous curry powder would be incomplete without it, too. 

Black or royal cumin is used less often in everyday cooking and more in festive dishes, but sparingly because of its strong flavor and aroma. Like its white counterpart, it is often dry-roasted whether used whole or powdered. Traditional garam masala intended for festive dishes also includes black cumin. Its aroma blends harmoniously with other spices to create the right balance. In many home kitchens, whole black cumin seeds are an essential in the spice drawer.   

Foods and spices to pair it with

In the Indian subcontinent, cumin is indispensable to dishes where meat, vegetables, or pulses are the main ingredient. From kebabs to potato bhaji and chickpea curry, hardly any dish goes without whole or powdered spice. Rice dishes and dips also rely on it to enhance the flavor. Blooming it in hot oil can flavor something as simple as plain rice and turn it into an aromatic side dish—for instance, the famous jeera rice. Among spices, it is routinely paired with turmeric, red chili or black pepper, coriander, cinnamon, cloves, and cardamom. 

If you have never cooked with it before, try this wonderfully simple recipe for cumin fried potatoes (Jeera Aloo) by Manali Singh. It’ll give you a taste of the flavor the amazing tiny seeds can produce! For a taste of dry-roasted cumin, this spiced yogurt (Jeera Raita) recipe is delicious! 

Middle Eastern and North African cuisines also celebrate the tiny seeds for their flavor and aroma in pretty much the same way—in meat stews, rice dishes, lentils, spice blends, and dips. Globally popular foods like hummus, falafel, shakshuka, and shawarma have cumin as a key ingredient. The famous Moroccan spice blend Ras al Hanout and Tunisian chili paste Harissa both use cumin seeds. While traditional Mexican cuisine does not rely heavily on it, its American version, Tex-Mex, adores the warm, earthy, aromatic seeds in seasonings and marinades.  

These days, alcoholic cocktails use it as a novel ingredient, but in the Indian subcontinent, cumin seeds have long been used in beverages. Jal-jeera (literally cumin water) is a refreshing summer drink made with lemon or tamarind, mint, black salt, and roasted seeds. The version of lemonade enjoyed across the Indian subcontinent to beat summer heat is often flavored with a pinch of roasted cumin powder.  

Whole VS ground: Which is better?  

White and black cumin seeds, whole or ground, are used depending on the purpose. The recipe and the cooking method determine whether to use whole seeds or ground, and whether to use the spice on its own or in a blend like garam masala. For a foundation or tadka (tempering), it’s whole seeds fried in oil or ghee. For sauces, gravies, rubs, marinades, dips, spreads, and beverages, it’s ground, dry-roasted seeds. For spice blends, too, it’s dry-roasted seeds ground in a mortar and pestle or grinder with other spices, such as coriander seeds, cinnamon, cardamom, and black pepper.  

The main difference between whole and ground cumin is shelf life. Whole seeds retain their flavor and aroma longer than cracked ones. When ground, their volatile oils get exposed to air, and their strength begins to fade. Whole seeds can last 2 to 3 years in an airtight container (minimal exposure to heat and moisture); ground cumin should be used within 6 months to 1 year for optimal flavor and aroma.

Does cumin spice have health benefits?

Cumin has long been used in traditional Persian and Indian medicine. Ancient Egyptians also knew of its health benefits. Modern scientific research has not yet proven its efficacy for all the ailments it has been traditionally used for; however, ongoing studies corroborate its medicinal properties and its potential as a remedy for many conditions.

Cumin seeds contain over 100 different chemicals. They are rich in micronutrients such as iron, potassium, magnesium, and calcium; contain fixed and volatile oils and essential fatty acids; and have antioxidant, anti-inflammatory, and antimicrobial properties. 

Traditional medicine used cumin to improve digestion, prevent bloating, soothe reflux and stomach cramps, and relieve diarrhea. High in vitamin C, ancient Persians used it to relieve chronic coughs, respiratory congestion, toothaches, and to treat epilepsy. 

Scientific studies have found cumin essential oil helpful for abdominal pain, bloating, and incomplete or sudden, compelling bowel movements. It has also been observed that using cumin significantly reduces fatigue, cold sweats, cramps, and backache in women during menstruation. Interestingly, trials indicate that using a cumin essential-oil-containing toothpaste can reduce dental plaque formation. Preliminary evidence also suggests that large doses of cumin can help improve blood glucose and lipid level regulation in patients with diabetes and cardiovascular disease. 

In Ayurveda, a simple tea prepared with white cumin helps improve digestion. This tea is made with cumin, coriander, and fennel seeds. When taken in the morning, after meals, or before bed, it relieves bloating and stress and restores the body’s balance. Here is a recipe for this simple and restorative healing tea. 

Dry-roasted whole cumin seeds, along with several other spices, salts, and herbs, are ground for an Ayurvedic spice mix called churan or churna. It is a common remedy prepared and stored in homes across the subcontinent that helps improve digestion and metabolism and removes toxins from the body.

Concluding words…

Like many other important spices, cumin has been recognized as a source of nutrition and health since ancient times, and revered as a gift from nature. When it becomes an essential part of cooking, food takes on its medicinal qualities and contributes to our overall health. No wonder, like other spices, it reached far corners of the world and became part of food and medicine. Today, it features in the iconic Lebanese Mujadar—a dish made from rice, lentils, and caramelized onion; the popular Mexican white rice; and culinary creations like spiced butter from Michelin-star chefs. These tiny seeds have not only conquered the world of taste, but science is also recognizing them for their medicinal effectiveness.
