Sesame Oil

Roasted vs unroasted — two different ingredients

Sesame oil divides into two fundamentally different products that often confuse home cooks:

Toasted (dark) sesame oil:

• Made from roasted sesame seeds
• Deep amber to brown color
• Strong nutty aroma
• Used as a finishing oil and seasoning, not for cooking
• Common in Korean, Chinese, Japanese cooking

Light (untoasted) sesame oil:

• Made from raw sesame seeds
• Pale yellow color
• Mild flavor
• Used for cooking, including high-heat applications
• Common in Indian and Middle Eastern cooking

Substituting one for another in recipes produces unintended results. Toasted sesame oil added to a stir-fry early would burn and produce bitter notes; light sesame oil drizzled on noodles wouldn’t provide the expected flavor.

A 4,000-year-old oil

Sesame is one of the oldest cultivated oilseed crops — domesticated in the Indian subcontinent and Mesopotamia at least 4,000 years ago. Sumerian and Babylonian texts mention sesame oil as both food and lamp fuel.

The Hebrew word “shemen” (oil) relates to sesame; ancient Egyptian texts mention sesame; and Chinese cultivation is attested from about 1100 BCE. The oil’s cultural breadth reflects sesame’s long agricultural success across multiple civilizations.

Korean and Japanese essentials

In Korean cuisine, toasted sesame oil is essentially a national flavor — a few drops finishes:

• Bibimbap (mixed rice bowl)
• Banchan (small side dishes)
• Marinades for bulgogi
• Korean tofu and vegetable preparations

In Japanese cuisine, toasted sesame oil flavors:

• Goma-ae (sesame-dressed vegetables)
• Ramen broths
• Various dipping sauces and marinades
• Sesame-encrusted tuna and other fish

A few drops at the end of a dish provides the unmistakable sesame fragrance — a defining characteristic of Korean and Japanese flavor profiles.

Indian and Middle Eastern sesame

In Indian cuisine, light sesame oil (called til ka tel) was historically an everyday cooking oil — particularly in southern India. The oil cooks at high temperatures without burning easily, making it suitable for tempering and stir-frying.

Indian cooking has shifted away from sesame oil toward other oils (coconut, peanut, sunflower, mustard) over the past century, but the traditional use persists in some regional cooking.

In Middle Eastern cuisine, sesame appears mostly in tahini (sesame paste) and seed form rather than as oil — though traditional Persian, Lebanese, and Yemeni cuisines all use sesame oils in specific dishes.

Toasted oil care

Toasted sesame oil has a relatively short shelf life — the toasted aromatics are volatile and degrade with heat, light, and time. For best flavor:

• Buy in small bottles
• Store in dark cupboards (not next to the stove)
• Refrigerate after opening if not used quickly
• Use within 3-6 months of opening

Some Asian cooks keep their toasted sesame oil in the refrigerator full-time, accepting the slight thickening for the longer freshness.

Mediterranean variations

In Greece, Turkey, and the Levant, sesame appears in sesamia (sesame brittle), halva (sesame paste sweetened with honey), and various savory and sweet sesame applications. Sesame oil is less common as a standalone cooking oil but appears in specialty regional dishes.

Cypriot cuisine has historically used sesame oil more than mainland Greek cooking, possibly reflecting closer ties to Anatolian and Levantine cooking traditions.
