Bento boxes of the week: Bamboo

This week I'm going back to the handcrafted bento boxes that I love. The material in the spotlight is bamboo.

Woven bamboo containers have been around probaby for thousands of years. Bamboo is a rapidly growing grass which has been under the spotlight recently because it's a sustainable plant material. It's water-resistant, durable and the leaves are said to have qualities. Here's a page with a history of bamboo used for food containers.

How practical is bamboo as a bento box? You obviously can't put anything very liquid in it. But it's great for solid things like onigiri and sandwiches. If you pack warm onigiri into a plastic container, it may get soggy by lunchtime, but by putting them a bamboo box, or wrapping them in dried bamboo leaves, the rice can 'breathe' without totally drying out. Wetter items can be packed in smaller containers that fit inside the box. Large bamboo bento boxes are very popular for taking along to _ohanami_, a picnic-party to appreciate cherry blossom trees, because they look so nice and are very lightweight. Imagine opening up several bamboo boxes filled with onigiri at a picnic! I wish I had more time to do things like that.

The bamboo bento boxes pictured above are from Taketora, a Japanese company that makes all their products by hand. The boxes range in price from 2,000 yen for this simple box made of white bamboo (shirotake) to a limited edition box made of bamboo leaves, which was designed by German architect Bruno Taut, for 12,000 yen. The ones pictured above are, from the left going clockwise 2,000 yen, 3,500 yen (this one is made of suzutake, a bamboo that retains a green color), and 3,800 yen.

What to look out for when shopping for bamboo food containers

  • Make sure that the item feels strong enough - cheap baskets and such are thin and flimsy.
  • A well made bamboo item should not have any splinters
  • Bamboo does not need to be lacquered to be water resistant, so beware of thickly lacquered items which may be masking cheap material underneath
  • Bamboo used for food containers is usually a a creamy white, a very light brown, or a light green in color, depending on the variety.

How to take care of bamboo food containers

Bamboo is quite water resistant. I use a couple of shallow bamboo baskets for cold soba (see one in action here); they are at least 15 years old and look as good as new. If it gets stained, wash it with dishwashing detergent and a non-scratching sponge, but otherwise you can just rinse it off in water. If rice grains get stuck, soak the container briefly in water and scrape off.

In Japan, where it's quite humid, baskets used for food are periodically put out in the sun to dry off completely. Since the climate is quite drier here in Switzerland, I do this maybe once or twice a year.

Japan's Bamboo Shoots: Dishes, History & Symbolism

Bamboo grows almost anywhere in Japan. Not only is it admired in places like Kyoto&#;s bamboo forest, it is also a versatile material for crafts and construction. It has another use not as well known overseas, however&#;food. Called takenoko in Japanese, bamboo shoots are one of many seasonal foods in Japan.

Japan&#;s Healthy Seasonal Ingredients

Seasonality is essential to Japanese cuisine, and the importance of shun, or seasonal ingredients, is reflected in the inventories of grocery stores nationwide. Not only do seasonal ingredients assure a healthy diet, they also tend to be symbolically charged. A characteristic ingredient of the spring season arrives at stores around March and sticks around until the end of May: takenoko, bamboo shoots.

Bamboo shoots are seen as an auspicious food and first appear around the same time as another herald of spring in Japan, the sakura cherry blossoms. The timing and symbolism of their literal breaking through ground make them the subject of haiku poems and even grants them their season in Japan&#;s old calendar.

Rarely used today, the old Japanese calendar contained 24 major seasonal divisions, each split again into three particular five-day periods. Within these 72 divisions, bamboo shoots receive their Japanese micro season around the 15th of May: &#;Bamboo Shoots Sprout&#;.

Edible Bamboo

Anyone only familiar with grown bamboo stalks might marvel at the idea of eating bamboo, but shoots that have yet to break the ground are soft enough to be eaten raw. However, unless you are an absolute takenoko lover heading out into the mountains to forage, you probably wouldn&#;t attempt this. Quite a few people do, though, paying close attention to the weather to harvest wild shoots at the right time.

When the shoots are exposed to sunlight and begin photosynthesis, they gain a sharp and bitter taste, essential when preparing them. Harvesting takenoko is a race against time, as they taste better when cooked right after harvesting. Regardless of the exact time of harvest, however, shoots need to be boiled for about an hour before they are ready to be enjoyed.

Popular Dishes

After boiling has eliminated their bitterness, takenoko are usually used for a variety of simple spring dishes such as:

Simmered bamboo shoots, Tosa-ni
Incredibly simple, this side dish involves simmering bamboo shoots in a katsuobushi (dried bonito) and soy sauce broth. It can be enjoyed as an appetizer, side dish, or with sake.

Takenoko Gohan

Bamboo shoot rice, is the most typical takenoko dish and a must-have in spring for most Japanese people. The crunchy and fragrant bamboo shoots are cooked with the rice, giving it a subtle earthy spring flavor.

Processed Bamboo Shoots

Takenoko is not just eaten at its freshest in spring; they are also used to make a condiment you have most likely already encountered if you&#;re a fan of Japanese ramen: menma.

Menma is bamboo shoots that have been boiled, dried, sliced, and fermented. A popular topping for all kinds of Japanese soups, it can also be a snack.

Unlike crunchy bamboo shoots, menma has a unique smooth yet tender texture. Its flavor is slightly salty but mild, so it does not overpower the soup it is served in.

What is the Symbolism of Bamboo in Japan?

Besides bamboo shoots&#; seasonal solid connection, the whole plant plays an important role all year round. Strong and fast-growing, it&#;s seen as a symbol of prosperity and vitality. 

An auspicious decoration made of cut bamboo stalks, pine, and plum tree branches called kadomatsu appears in pairs at the entrance to Japanese houses over the New Year&#;s period. Representing prosperity, longevity, and steadfastness, respectively, they invite in a fortune-bringing deity known as toshigami. 

Bamboo is also a good-luck symbol. Image via Shutterstock

Bamboo is also central to Japan&#;s oldest work of fiction: The Tale of the Bamboo Cutter, also known as the Tale of Princess Kaguya. Written by an unknown author in the late 9th or early 10th century, the story revolves around a princess from the moon, discovered as a baby by a poor bamboo cutter within a glowing bamboo stalk.

Beyond its deliciousness and symbolism, bamboo is still essential for Japanese food and drink preparation. There would be no sushi rolls without makisu, a bamboo rolling mat, and no Japanese tea ceremony without chasen, a bamboo whisk used to make matcha tea.

Bamboo continues to be necessary to Japan, and for good reason. Have you tried eating bamboo before? Let us know your thoughts in the comments below!
