Traditionally, the key ingredients in the Japanese dish shira-ae are white – white tofu, white miso and white sesame seeds; shiro means white in Japanese and the ae suffix denotes a vegetable dish with dressing. What’s unusual from my European perspective is the low amount of liquid ingredients in the dressing; the silken tofu provides both additional moisture and the body of the sauce.
This can be also used with other greens such as spinach or seaweed, or your own selection of vegetables.
Here’s the recipe. To learn more about the ingredients, keep reading.
Saya Ingen Shira-ae
Green Beans with a Tofu, Miso & Sesame Dressing.
- 300 grams green beans
- 100 grams silken tofu (pressed tofu is not suitable for this recipe)
- 50 grams sesame seeds , lightly toasted
- 2 tsp miso paste
- 2 tsp sugar
- 2 tsp mirin (rice wine)
Shira-ae traditionally uses white miso paste, the mildest and sweetest miso. I prefer the saltier and more pungent flavour of red miso, so it’s the type I most commonly have in the fridge. Red miso gives my shira-ae dressing a darker colour than it would have if I used white miso.
Note: I have used Clearspring organic tofu, a long life firm silken tofu made with organic soy beans, spring water from Mount Fuji and nigari, a naturally occurring mineral rich coagulant derived from sea water. See below for my tofu lowdown.
Prepare and cook the green beans as you like them. My preference is that they have a little crunch left in them.
Once cooked, drain and tip into a bowl of cold water to stop them cooking further.
In the meantime, grind the sesame seeds using a mortar and pestle, food processor or spice grinder.
Mix the ground sesame seeds with the miso paste, sugar, mirin and tofu. Silken tofu is so soft and moist it will easily break up and combine with the other ingredients.
Drain the beans well and mix with the dressing.
Tofu, Miso and Sesame Seeds
Tofu is made by coagulating soy milk (itself made by soaking, grinding and heating soy beans and water) and straining the resulting curd. Originating in China about 2000 years ago, the technique spread to Korea and then Japan in the 8th century, coinciding with the spread of Buddhism – tofu is an important source of protein in a Buddhist vegetarian diet.
Incidentally, if you ever wondered about the English-language name, it’s taken directly from the Japanese, which is itself taken from the Chinese dòufu. Dòufu translates as “bean” “curdled”, giving us the name that is more prevalent in the United States – bean curd.
The variety of tofu available in East Asia is amazing!
Broadly speaking, tofu products divide into fresh and processed.
Fresh tofu comes in many different textures, the result of a range of different coagulants used to make it as well as differing production techniques.
Silken tofu is the softest kind and, because it’s not curdled, strained or pressed after coagulation, it has a really high moisture content. You can find both soft and firm silken tofu, but both are far softer and wetter than pressed tofu.
Firm tofu does retain a fair amount of moisture, but not as much as silken tofu. Its surface often retains the pattern of the muslin or mould used to strain and press it. The firmest tofu is pressed rigorously and has an almost rubbery texture, a little like paneer or halloumi.
There are also a number of processed tofu products included fermented, pickled and dried tofu. These include stinky tofu, which smells much like a very ripe soft European cheese. Just like cheese, it tastes far better than it smells!
Dried tofu is very light, does not need to be refrigerated and is usually rehydrated before use. There are many shapes and textures available.
Another type is frozen tofu. Large ice crystals, which form on freezing, leave cavities when the tofu is defrosted, creating a spongy texture. This type of tofu is often sold cubed and freeze dried.
Tofu can also be deep fried, usually after being cut into cubes or triangles, or into thinner pieces to create pouches for inari-zushi. Obviously, the firmer and drier types of tofu are better for frying.
These days, tofu is readily available in the UK, though you won’t find the sheer variety available in Asia!
It is often associated in the West with a vegetarian or vegan diet, with detractors dismissing it as bland and unappetising. Personally, I love the stuff. Yes, the flavour is subtle but it’s a very versatile ingredient. It’s also very healthy as it’s high in protein but relatively low in calories and fat. Depending on the coagulating agent used, it can also be high in calcium and magnesium.
Miso is made by fermenting soybeans, and sometimes additional grains such as rice or barley, with a fungus known in Japanese as kōjikin. The resulting paste is used as a seasoning throughout Japanese cooking. There are many, many different varieties available in Japan, often broadly divided by their colour. White is the mildest and sweetest. Red, aged for longer, is stronger and saltier and darkens with age through red into brown.
Sesame seed is oldest known oilseed crop, with archeological evidence suggesting it was already being cultivated 5500 years ago. Sesame seeds have a very high oil content and the oil itself is very stable with a long shelf life, making it easy to store in hot climates. Once the oil has been extracted from the seeds, the protein-rich remaining meal can be used as animal feed.
Most wild species are native to sub-Saharan Africa, where the genus originated, but the cultivated type, Sesame Indicum, originated in India. A hardy, drought-tolerant crop, sesame is now grown in tropical regions around the world with Burma, India and China the biggest producers (in 2010).
Of course, the seeds are popular in seed form too; they feature in many cuisines around the world, far too many dishes to list here.
Pale straw-coloured “white” seeds are the most common, but black varieties can be very striking, especially when combined with the white. I loved the jin doy spheres I enjoyed at A Wong a few months ago.
I love this tidbit from Wiki’s page on sesame seeds: “Upon ripening, sesame fruit capsules split, releasing the seeds with a pop. It has been suggested that this is root of the phrase “Open Sesame” in the historic fable of Ali Baba and the Forty Thieves in One Thousand and One Nights. The opening of the capsule releases the treasure of sesame seeds.”
Suribachi & Surikogi
One of my favourite purchases from our last visit to Japan was a beautiful suribachi (grinding bowl) and surikogi (wooden grinder). This very Japanese mortar and pestle is perfect for grinding sesame seeds, which are quickly pulverised against the ridged inner surface of the bowl.
Did you know that Iwo Jima’s Mount Suribachi was named for this humble kitchen tool?
This dish is such a quick and easy one to make and is both healthy and utterly delicious. I hope you enjoy it and do please leave me a comment to let me know what you think!

Really like how thick,mellow and full that recipe looks. X
It’s a lovely rich dressing, completely unlike the liquid ones we pour over salads.
I love green beans with anything – but this looks really tasty so I’d love to give it a go. I’m a big fan of miso but not so confident with tofu. Thanks for the tips.
Ren, this silky tofu is perfect in this as it has a high liquid content, and mixes easily. Hope you liked.
Interesting recipe. I love the look of the grinding bowl and grinder
Thanks, I love our suribachi!
Oh my! I neeeeeeed miso now
And always… 😉
I love sesame seeds and miso so this recipe sounds amazing Kavey!
Thanks Margot, it’s a Japanese classic. I love it too!
