Sesame Seeds

Look for plump, uniform seeds with a clean, nutty aroma and no mustiness; white, black, and golden varieties are sold whole and hulled or unhulled. Unhulled seeds are darker, more flavorful, and higher in calcium; hulled seeds are milder and lighter. Buy from a source with good turnover, as sesame's oils can go rancid.

For tahini, choose pure, single-ingredient tahini (only sesame, no added oil or salt) — Lebanese, Israeli, and Palestinian brands are prized. For sesame oil, seek cold-pressed, unrefined toasted sesame oil for flavor (a little goes a long way); light sesame oil is a separate, neutral cooking oil. For sweets, look for fresh-made halva and sesame brittle from Middle Eastern or Indian shops.

Season: sesame is a warm-season annual, planted in spring and harvested in late summer to fall when the pods ripen; the dried seeds, tahini, and oil are available year-round, with the freshest seeds from the autumn harvest.

Harvesting: Sesame is an annual plant grown in warm, dry climates; the tubular flowers develop into pods that split open at maturity and scatter their seeds — which is why harvest must be timed carefully, often cutting the stalks before the pods burst. The pods are then dried and threshed to release the seeds.

Hulling & cleaning: After threshing, the seeds are cleaned; for white sesame, the hull is removed (often by a wet process) to reveal the pale kernel. Unhulled seeds keep their seed coat (and more calcium and fiber) and are darker; the choice between hulled and unhulled is one of flavor, texture, and nutrition.

Grinding & pressing: To make tahini, sesame seeds are soaked, hulled, toasted lightly, and ground into a smooth paste. To make sesame oil, the seeds are pressed — cold-pressing for light cooking oil, and roasting then pressing for the intensely flavored toasted sesame oil of East Asian cuisine.

Drying: Fully dried whole sesame seeds keep for up to a year in a sealed, cool, dry container — the seed coat protects the oil, making sesame one of the best-storing seeds; the dried seed is the base for all other sesame products.

Pressing into oil: Sesame oil is one of the oldest ways to preserve the seed's value — pressed oil keeps for months to a year, far longer than the fresh seed's delicate aromas; sesame oil was one of the first cooking oils in human history, prized for its stability and flavor.

Sweets & pastes: Tahini, halva, and sesame brittle are preserving innovations — grinding and sweetening the seeds into stable, long-keeping foods; halva keeps for weeks at room temperature, and tahini for months refrigerated, carrying sesame's nutrition through the year.

Sesame seeds are rich in healthy fats (mostly polyunsaturated and monounsaturated), protein, and dietary fiber, making them a concentrated source of plant-based energy and nutrition; they are also one of the best plant sources of calcium, especially unhulled black sesame, which has far more calcium than hulled white.

Sesame is high in magnesium, iron, zinc, copper, and B vitamins, and especially in lignans (sesamin and sesamolin) — antioxidant compounds unique to sesame that support heart health, liver function, and hormone balance. The oil's antioxidants make it one of the most stable cooking oils, resisting rancidity.

Sesame is naturally gluten-free and a good protein source for vegetarian and vegan diets, especially through tahini; black sesame is prized in traditional Chinese medicine for kidney and blood health, and sesame is eaten across cultures for energy, longevity, and warmth in the cold season.

The phrase "open sesame" from the Arabian Nights may come from the way ripe sesame pods burst open suddenly at the slightest touch, scattering their seeds — a magical image that gave sesame its place in folklore; the seed was sacred in ancient Babylon, Egypt, and India, used in ritual, medicine, and as currency.

Sesame is one of the oldest cultivated oilseed crops, grown for over 5,000 years — the ancient world pressed it for oil long before olive oil; the plant traveled the Silk Road into China and Japan, where it became central to cuisine, and into Africa, where the name 'benne' (from West African languages) is still used in the American South for the sesame brought by enslaved Africans.

Sesame oil is one of the most stable cooking oils on Earth thanks to its unique antioxidants (sesamin, sesamol, and sesamolin), which prevent rancidity; this is why sesame oil was used to preserve and finish foods long before refrigeration, and why it is still used in massage and Ayurvedic medicine for its stability and skin benefits.

In India, sesame (til) is sacred to Makar Sankranti, the harvest festival marking the sun's northward turn — til-gud sweets (sesame and jaggery) are exchanged with the saying 'eat sesame and jaggery, speak sweet words,' symbolizing warmth, friendship, and good fortune in the cold season; sesame links the harvest, the sun, and human goodwill.

From India's Sankranti to China's Lunar New Year and Japan's Ohagi, sesame is celebrated across Asia and the Middle East:

Drought-tolerant & low-input: Sesame is a hardy, drought-tolerant crop that grows well in poor soils with little water, making it an important and low-impact crop for smallholder farmers in arid regions; it needs far less water than most oilseed crops and thrives where other crops fail.

Smallholder farming: Most sesame is grown by smallholder farmers in India, China, Sudan, Tanzania, and the Sahel; supporting fair-trade and sustainably grown sesame supports these farming communities and preserves the traditional sesame varieties and processing methods of the Middle East, Africa, and Asia.

Pollinator-friendly: Sesame's tubular flowers attract bees and other pollinators, supporting biodiversity in sesame-growing regions; the plant's hardiness and low input needs make it a resilient crop for climate-adapted agriculture in the dry tropics and subtropics.

Global range: Sesame originated in Africa and India and has been cultivated across the Middle East, South and East Asia, Africa, and the Mediterranean for millennia; today it is grown mainly in India, China, Sudan, Tanzania, Myanmar, and Nigeria — a tiny seed that crossed the ancient world and feeds billions.
