Sesame salt is one of those pantry basics that does quiet, useful work: it sharpens plain rice, gives vegetables a little more character, and makes a bento feel finished without adding another sauce. What many people call gomo shio is better known as sesame salt, or gomashio, and it earns its place because it is simple, fast, and genuinely versatile. In this guide I’ll show what it is, how I make it, where it works best, and how to keep a jar fresh in a UK kitchen.
A few facts worth keeping close before you start
- It is a dry seasoning made from toasted sesame seeds and salt, usually lightly crushed for texture.
- A good home ratio is usually somewhere between 10:1 and 15:1 sesame to salt by weight, depending on how salty you want it.
- It works best as a finishing condiment on rice, onigiri, vegetables, tofu, eggs, and bento components.
- A suribachi helps because it crushes the seeds without turning them into powder.
- Freshness matters more than with many other dry seasonings, so small batches are often the smarter choice.
What sesame salt is and why Japanese kitchens keep it nearby
Sesame salt is not a sauce and it is not a full furikake blend. It sits in a very useful middle ground: drier and simpler than a topping mix, but more aromatic than plain salt. Toasted sesame seeds bring nuttiness and a little crunch, while the salt keeps the seasoning grounded and useful on plain food.
That is exactly why it belongs in a pantry essentials list. I reach for it when a bowl of rice is technically cooked but still feels flat, or when a plate of greens needs something more than steam and good intentions. It solves the last 5% of seasoning without asking me to make a dressing, heat a pan, or open half the cupboard.
In Japanese home cooking, that small improvement matters. A simple sprinkle can make a modest meal feel more complete, and once you see it that way, the next question becomes how to make a batch that tastes balanced rather than blunt.
How to make a batch that tastes balanced, not blunt
The safest way to think about the seasoning is by ratio. I like to start with a balanced blend and then adjust upward or downward depending on how I plan to use it. If I want something I can sprinkle generously over rice, I lean milder; if I want a sharper table seasoning, I move closer to the salt end.
| Sesame to salt ratio | Flavour profile | Best use |
|---|---|---|
| 15:1 | Mild, sesame-forward | Frequent sprinkling over rice, vegetables, and tofu |
| 10:1 | Balanced and classic | Everyday table jar and bento use |
| 8:1 | Saltier and more direct | When you want a firmer savoury finish |
My process is straightforward. I toast the sesame seeds gently in a dry pan for a couple of minutes until they smell nutty, then I let them cool for a moment before crushing them. A suribachi, which is a ridged Japanese mortar, gives the best texture because it breaks the seeds without turning everything into dust. A spice grinder works too, but I stop early; if the mixture becomes too fine, it loses the texture that makes it appealing.
- Toast the sesame seeds over low heat for 2 to 3 minutes, stirring so they do not burn.
- Let them cool briefly so the oils settle and the aroma stays clean.
- Crush most of the seeds lightly, but leave some whole for texture.
- Mix in the salt and taste a pinch before adding more.
- Store the finished seasoning in a dry, airtight jar.
I usually leave about a third of the seeds whole. That small contrast is what makes the seasoning feel fresh rather than dusty, and it is the difference between a bland sprinkle and one that actually changes the bite. Once the jar is ready, the best way to judge it is not by smell alone, but by how it behaves on a bowl of rice or a simple lunchbox.
Where it works best in bento and everyday meals
This is the part that makes the seasoning feel indispensable. In a bento, every component has to earn its place, and a light shower of sesame salt can do that with almost no effort. It brings plain rice back to life, helps vegetables taste deliberate instead of incidental, and gives a lunchbox a finished look without making it heavy.
- Steamed rice - a light sprinkle over hot rice is the classic use, and the simplest one. I use about 1/4 to 1/2 teaspoon per bowl, depending on size.
- Onigiri - add it just before wrapping or shaping so the rice stays fragrant and the surface has a little grip.
- Blanched greens - spinach, green beans, and broccoli all benefit from a small finish, especially when dressed lightly.
- Tamagoyaki - a tiny pinch can balance the sweetness of Japanese rolled omelette without turning it savoury in the wrong way.
- Tofu and grain bowls - cold tofu, barley rice, and mixed grain bowls all welcome the extra aroma and crunch.
What I would avoid is using it on dishes that already carry a strong sauce or heavy seasoning. It works best when the food is restrained and needs a lift, not when the plate is already crowded. That is also why it fits so naturally into bento culture: it finishes food rather than competing with it.
From there, the real practical question becomes how to keep it fresh enough to taste good every time you open the jar.
How to store it and decide whether to buy or make
Sesame seeds contain natural oils, so freshness matters more than it does with many other pantry seasonings. If the jar sits too long in heat or humidity, the aroma dulls first, and the seasoning loses the very thing that makes it worth keeping. In my kitchen, I treat it like a small, fast-moving condiment rather than something to leave untouched for months.
| Option | Best for | Trade-off | My take |
|---|---|---|---|
| Homemade | Fresh aroma and full control over salt level | Needs a few minutes and small batches | Best if you use it weekly or want a milder blend |
| Store-bought | Convenience and consistency | Usually saltier and less customisable | Best as a backup jar or for very busy weeks |
For storage, I keep it in a small airtight jar, away from the cooker and out of direct light. If your kitchen is warm, the fridge is sensible; if it stays cool, a cupboard is usually fine. In the UK, I would look for it in Japanese grocers, larger Asian supermarkets, or specialist online shops if I did not want to make it myself. The main thing is not the retailer, but the freshness of the seeds and the tightness of the lid.
If you want the seasoning to stay useful rather than merely available, the next step is to think about small variations that change the flavour without turning it into a different product.
Small variations that keep the idea useful
I do not think sesame salt needs many embellishments, but a few restrained variations are genuinely worth knowing. They let you match the seasoning to the meal instead of forcing one jar to do everything.
White sesame version
This is the most all-purpose option. The flavour is clean, the colour stays light on rice, and it blends quietly into bento boxes without drawing attention to itself. If you want one jar to keep on the table every day, this is usually the version I would choose first.
Black sesame version
Black sesame gives a deeper, slightly more dramatic flavour and a stronger visual contrast. I like it on plain rice, sweet potato rice, and simple lunchbox meals where I want the topping to look intentional. It tastes a little richer, so it can feel more special even when the ingredients are basic.

A more savoury version with seaweed
If you add a small amount of shredded nori or seaweed flakes, the seasoning moves closer to furikake. That can be useful for bento, but I keep the addition modest because too much extra dry matter changes the balance fast. If you want the seaweed note, add it for aroma, not bulk.
There is a limit to how far I would push the variations. Once sugar, seaweed, or extra spices start taking over, you are no longer adjusting sesame salt, you are building a different condiment. That is fine, but it is a different job, and the original version is valued precisely because it stays simple.
Why this tiny jar earns permanent space next to the rice
If I were stocking a compact Japanese pantry from scratch, sesame salt would be one of the first dry seasonings I set beside the rice. It is cheap to make, easy to adjust, and useful in a way that never feels fussy. In a UK pantry, I think of it the same way I think of flaky salt or a good mustard: small, unassuming, and far more practical than its size suggests.
Keep the batch small, toast gently, and use it at the table where plain food needs a little lift. That is usually enough to make the seasoning earn its place for good.
