Nanohana no Kurashie: A Recipe for Spring in Japan

This post first appeared over at ecotwaza (back when the address was back in April, 2012. The recipe, though, is an absolute classic and worth rolling out once again. (Please do note the point about wasabi at the end, though.) So, while we continue to unpack and settle into our new apartment, I'll leave you to read, make a shopping list, and then enjoy! - jb

Komatsuna gone to seed, a.k.a. nanohana.
With the moon in the east
And the sun in the west.
  • Yosa Buson, 1716-1783
One of spring's first greens (or winter's last, depending on how you look at it) nanohana 菜の花 are as cheerful as they are delicious with their bright green leaves and yellow flowers. It's easy to imagine the signature bright blooms glowing in the mix of first and last light that inspired Buson, a contemporary of Basho's and a famous poet in his own right, to pen the above haiku. Nanohana, usually the stems and leaves of rape seed Brassica napus, remains a favorite spring vegetable.

Arriving earlier than sakura (cherry blossoms) and lasting a bit longer, these energetic bloomers can be found growing in orderly rows in public parks as well as lining the embankment next to the Yamanote Line. These days, too, community gardens and local farms will prominently feature this spring delicacy. Tightly bunched at the supermarket or loosely bagged at a nearby chokubaijo (direct sale stand) or farmer's market, they are a delightful addition to the table. (BioFarm, an organic farm and restaurant in Chiba, grows a fantastic variety from komatsuna, pak choi, and haksai (chinese cabbage) that shoppers at the Earth Day Market can peruse to find their favorite flavors. Be sure to go early, though, for the best selection!)

Mouth-wateringly spring.
Our local izakaya served up a beautiful plate of them the other night, and the mistress there shared her recipe for this spicy spring dish. Nanohana certainly makes the wait for summer vegetables a little easier!

Nanohana no Kurashie*
1 bunch nanohana (Any variety is fine. It will include stems, leaves and a few flowers either blooming or just about to bloom.)
1 ½ Tbsp. Soy sauce
2 Tbsp. Dashi
Bonito flakes, to taste (optional)
½ Tsp. Karashie mustard**

  1. Fill a pan with water and bring it to a good rolling boil. Make sure the lid is on so it goes a bit faster.
  2. Pop the nanohana into the boiling water and replace the cover. Boil for about 4 minutes or until the stems are soft but still have a bit of crunch to them.
  3. Drain and rinse the nanohana in cold water for several seconds. This quick cooling stops the cooking process and helps retain some of the nutrition as well as crunch. (Remember, too, to save that cooking water for making soup or rice later on!)
  4. Gently squeeze out excess water and then cut the nanohana into two-inch (four-centimeter) length pieces.
  5. In a separate bowl, mix together the dashi, soy sauce, and mustard thoroughly.
  6. Add the nanohana and give it a good stir to fully spread out the flavor of the sauce.
  7. Chill in the refrigerator or serve immediately.

*Not so keen on spice? Simply eliminate the mustard and enjoy the brilliant taste of Ohitashi, another classic spring dish!

**I used the kind that comes in the tube, but it should also be possible to use dry mustard. You'll have to report back if you try the other variety. I also don't recommend substituting wasabi. It's terrible.

Finding Heirloom Seeds in Japan

Drying pods of heirloom Hutterite Soup Beans. Since moving to Japan eight years ago, one of my greatest challenges as a farmer-gardener has been to find heirloom or open-pollinated seeds. The majority of seeds available are not GMO (genetically modified organisms) as Japan, at this point, doesn't accept this material. Most seeds, though, are nearly all F1 varieties. Heirloom and F1 Varieties In plant breeding, F1 is the name given to the first generation of a cross between two true breeding parents. For example, if I decide to cross an Amish Paste Tomato with another heirloom variety tomato such as Emmy, in hopes of getting a gold paste tomato, the resulting generation of fruit is F1. In order to get that tomato of my culinary dreams, I'll need to choose members of that first generation that are headed in a direction I like - early ripening, medium-sized fruit, good taste - and save their seeds. I'll plant them and repeat the process again and again over time unti

Satoimo: One of Japan's Favorite Slimy Things

Satoimo in all their hairy glory. This post first appeared in slightly different form on Garden to Table as part of the 2012  Blogathon . The website has since moved on to the ether, but the post is still a good one. After all, people here are still eating satoimo on a daily basis, and many others are just seeing these little potato-like objects for the first time. Enjoy! Satoimo is one of Japan's odder vegetables. Under it's rough, slightly furry skin is white flesh that is a little bit slimy even raw, and with a gentle nutty flavor.* Baked, grilled, steamed with dashi, or deep-fried satoimo stands well on its own or paired up with other vegetables and meats in a wide variety of soups and stews . (The leaves are also edible.) Satoimo stores well, and like any root crop worth the effort, stocks are just running low on this household favorite as the farmers in my area of Tokyo get ready to put a new crop in the ground in May. I cannot say I was a fan of this l

Goma Ai Shingiku - Sesame and Chrysanthemum Greens

Last week I had the pleasure of helping some friends work in their parents garden not too far away. Tucked behind the house, the garden sits on a former house lot. When it came up for sale about five years ago, my friend's father jumped at the chance. Open land in Tokyo can be hard to find and expensive, but for a retired professional looking for a little spot to till in the city it was an opportunity to good to pass up. Now, it is a garden to envy. As we came through the gate rose, lily, and peony blooms greeted us with great shouts of color while rows of vegetables stood tidily at attention on the sunny center stage. Small fruit trees along with one of the biggest sansho trees I've seen yet stood quietly here and there. Near waist-high sweet corn, bushy young potato plants, cherry tomatoes, eggplants, and beans were preparing their summer fruits, while a handful of still quite luscious looking winter vegetables like komatsuna, mizuna, and kabu held one last ro
