Cook with
Toasted seeds and oil that add nutty aroma across Japanese, Korean and Chinese dishes.
Sesame runs quietly through almost every East Asian kitchen, lending a warm, toasty nuttiness that underpins far more dishes than it ever headlines. The tiny seeds appear toasted as a garnish, ground into pastes and dressings, and pressed into the fragrant oil that finishes countless stir-fries and noodle bowls. Mild on their own, they bloom into something rich and deeply savoury once heat is applied, which is why toasting is almost always the first step.
Sesame comes as small flat seeds in two main forms: hulled white seeds, which are mild and sweetly nutty, and unhulled black seeds, which are earthier and a touch bitter with a bolder colour. Raw, both are unremarkable; toasted, they release a deep, roasted aroma. The same seeds, pressed after roasting, yield toasted sesame oil — amber, intensely fragrant, and used by the spoonful as a seasoning rather than a frying fat. Ground further, toasted seeds become a paste that bodies out dressings and sauces. White seeds are also often left whole as a coating, clinging to dumplings, breads and fried foods where they crisp and colour in the heat.
To toast seeds, spread them in a dry pan over medium heat and shake or stir constantly until they turn golden and smell nutty, just a few minutes; they scorch quickly once they colour, so they must not be left unwatched. Cool them before storing or grinding. For a sesame dressing, toasted seeds are pounded or blitzed with a little oil and seasoning until coarse or smooth. Toasted sesame oil is added only at the end of cooking, off the heat, or stirred into dips and dressings — heating it hard destroys its fragrance and turns it bitter.
Seeds are sold raw or pre-toasted; buying raw and toasting at home gives the freshest aroma. Choose plump, uniform seeds and oil that is clearly labelled toasted or roasted for fragrance, as opposed to pale, neutral cold-pressed sesame oil. Being oil-rich, sesame is prone to going rancid, so seal seeds and oil tightly and keep them cool and dark, or refrigerate for longer life. A sharp, off, paint-like smell means the oils have spoiled and it is time to start fresh.
Sesame is everywhere in this cooking: toasted seeds and oil season the vegetables of bibimbap, the oil perfumes the marinade for bulgogi, and seeds finish a bowl of japchae glass noodles. A drizzle of the oil lifts countless stir-fries and dressings. If toasted seeds run out, a quick toast of raw ones is the fix; there is no real substitute for the oil’s fragrance.

They come from the same plant but differ in flavour and use. White (hulled) seeds are mild, slightly sweet and nutty, and are the everyday choice for toasting, coating and garnishing. Black sesame seeds keep their dark hull, giving a stronger, earthier, more bitter-edged flavour and a striking colour, which is why they often appear as a finishing garnish or ground into desserts. The two can be mixed for visual contrast, but where a clean nutty taste is wanted, white seeds are usually preferred.
Raw sesame seeds taste flat, but a brief toast transforms them, drawing out a deep, warm nuttiness and a pleasant aroma. Heat develops the oils in the seed, which is where the flavour lives. Toasting also gives garnish seeds a faint crunch and a golden colour that looks far more appetising than pale raw ones. The same principle is why toasted sesame oil, pressed from roasted seeds, is so much more fragrant than the plain cold-pressed kind.
No, it is a finishing oil, not a cooking fat. Its low smoke point means it scorches and turns bitter over high heat, and its intense fragrance would be wasted and dulled by prolonged cooking. Add it off the heat at the very end of a dish, or stir it into dressings and dips, where a small amount carries a big aroma. For actual frying, use a neutral high-smoke-point oil and save the sesame oil for the last flourish.
Because sesame is rich in oil it can turn rancid, so cool, dark storage matters. Keep seeds in an airtight jar in a cupboard for a few months, or in the fridge or freezer for longer, where toasted seeds especially hold their aroma. Toasted sesame oil should be sealed tightly and kept away from heat and light; refrigeration extends its life considerably. A rancid, paint-like smell from either is the sign to replace it.
