Botanical Origins: Different Families, Distinct Seeds
While often mistaken for one another due to their small size and use as oilseeds, til and mustard seeds hail from entirely separate plant families. Til, known scientifically as Sesamum indicum, is a member of the Sesamum genus and has numerous wild relatives native to Africa. The domesticated version originated in India over 3,000 years ago and grows in pods. Mustard seeds, on the other hand, belong to the Brassica genus, which is part of the broader cabbage family (Brassicaceae), a family that also includes broccoli, kale, and turnips. Depending on the variety, mustard seeds can be yellow/white (Sinapis alba), brown (Brassica juncea), or black (Brassica nigra), each with its own flavor profile.
Physical and Flavor Profile Differences
The most significant distinction between these seeds lies in their physical appearance and flavor. Sesame seeds are generally flat and ovate, ranging in color from off-white to golden-brown (hulled) or black (unhulled). They possess a rich, nutty, and slightly sweet flavor, which is enhanced when toasted. Mustard seeds, in contrast, are smaller and perfectly round. Their color varies from yellow to dark brown/black, and they are known for their pungent, peppery, and sharp taste, which becomes milder and nuttier when tempered in hot oil.
Nutritional and Chemical Composition
Both seeds are nutritional powerhouses, but their chemical and fatty acid compositions differ significantly. Sesame seeds are particularly known for their high content of healthy polyunsaturated and monounsaturated fats, fiber, and plant compounds called lignans, which have antioxidant and anti-inflammatory properties. They are also an excellent source of minerals such as calcium, magnesium, copper, and iron. Mustard oil, and therefore mustard seeds, contain a high level of monounsaturated fats, including erucic acid, though levels are regulated in some regions. Brown mustard seeds, in particular, contain a compound called allyl isothiocyanate, which is responsible for its characteristic pungent flavor.
Culinary Applications in Global Cuisine
Their different flavor profiles lead to very different culinary uses around the world. Sesame seeds are commonly used whole, or ground into a paste (tahini), as a garnish for baked goods, in sauces, salad dressings, and Middle Eastern dishes like hummus. Sesame oil, particularly toasted sesame oil, is a flavorful finishing oil in Asian cooking. Mustard seeds, particularly brown and black varieties, are fundamental to Indian and Bengali cuisine, where they are often tempered in hot oil to release their nutty flavor. They are also central to the condiment mustard, pickles, and some Eastern European cooking.
Growing Conditions and Agricultural Practices
Til (Sesamum indicum) is a robust, drought-tolerant crop that originated in India and thrives in warm climates. It is a survivor crop, able to grow even when rains fail. The seeds grow inside pods that burst open when ripe, a process that once required careful manual harvesting but has led to the development of indehiscent (non-shattering) varieties for mechanical harvesting. Mustard plants, on the other hand, prefer temperate climates and well-drained soil. The different types of mustard are grown in various regions, with Canada and Nepal being major producers today. Some varieties are also used as cover crops to naturally suppress pests.

Conclusion: Understanding the Distinct Seeds
To answer the question, "Is til the same as mustard?" with a definitive "No" is to appreciate the rich diversity of seeds used in global cuisine. While both have ancient origins and are prized for their oils and nutrients, they are entirely different botanically and possess unique characteristics. Til, or sesame, provides a nutty sweetness, making it a versatile addition to many dishes and a key ingredient in pastes like tahini. Mustard, on the other hand, offers a pungent, peppery heat that is essential for tempering and creating bold condiments. Recognizing the difference between these two seeds enhances one's understanding of their unique contributions to flavor and nutrition. So, the next time you encounter a recipe calling for one or the other, you'll know precisely which distinct seed to reach for.
