Sweet Potato Harvest: Reprise

It's almost impossible to believe that nearly five years have passed since I set foot on the  family farm here in Tokyo. My time there has easily been the best part of my life in Japan. The Arai's have become some combination of family and friend to me. As we ponder our next move, I can hardly bear the thought of not having C-chan and Takashi-san as part of my daily life. So, as I type this with tears in my eyes, I'm going to share again one of my favorite farm happenings: the sweet potato harvest. It's early writing, so bear with me to the recipe near the end. It's one of my favorites and worth the wait! - JB

Two kinds of sweet potatoes, both delicious.

This Spring I planted sweet potatoes for the first time. I'd certainly eaten them, and given some thought to growing them, but space in my garden often felt like it was at a premium. And past experience taught me that the potato can be a master of disguise resulting in a surprise second year harvest.

The Planting
When the Takashi's mentioned that an adjacent field was to be planted in sweet potatoes, I veritably begged to be able to help. We'd discussed our mutual fondness for them after I'd made some sweet potato stew for Shee-chan when she was feeling under the weather, as well as the differences between the American and Japanese sweet potatoes. (Japanese sweet potatoes have the same purple skin but are yellow on the inside. They also tend to turn brown rather quickly after slicing up, and the consistently is a bit more starchy.)

One fine morning in May found me with gloves, hoe, hat, and Takashi-san at the field. He had already tilled, but the sweet potato beds still needed a bit of preparation. Using stakes and ropes we created straight lines along which I hilled the soil into a long mound where I later planted the slips. Takashi-san worked on another part of the farm returning periodically to check my progress and admonish me to work a bit slower to save my back. Ten rows later I was done and ready for lunch.

The slips came bundled in newspaper, and we moved along the rows sticking them in the ground at intervals of about a foot and a half. Well, not really "sticking" but rather laying the slip (a sweet potato leaf and stem with a tiny root bud at the bottom) on the soil and then simply covering it up. Once the sprinkler system was up and running smoothly the days work was done.

The field was watered in the early mornings and late evenings as needed. (Last year the Takashi's watered by hand, and decided that was the last time for that.) I asked about applying any compost or dung, but the Takashi's said the sweet potato only required regular watering. It made me think what a boon this vegetable must be in some ways. It required some work to get in the ground and some watering, but no additional compost or fertilizer. Just let it grow and a good harvest was nearly assured.

Over the summer I would look over and see the vines stretching about the field soaking up sun and rain. Weeds grew alongside the plants, and in time the vines weren't even visible. I worried occasionally that the sweet potatoes weren't there any more - lost to the weeds or some unknown calamity that the Takashi's were too kind to tell me about - but then I remembered how clever and determined the potato can be and let it go.

The Harvest
Last Saturday we harvested some of the biggest, most beautiful sweet potatoes I've ever seen. Well, I didn't harvest them at all, but rather a group of preschool children and their parents did. Decked out in rubber boots with trowels in gloved hands children ranging in age from a few months (in one case strapped to a father's chest in a baby carrier) to about five with parents lined up along the rows.

The look on the faces of children and adults alike as HUGE purple sweet potatoes emerged from rich black soil was utterly priceless. Pure pleasure reigned supreme as potato after potato was added to piles all over the field. Kids dug for them like buried treasure and ran around holding them aloft. Kids ate dirt (and cried a little when finding it wasn't quite as tasty as anticipated), rolled in dirt, walked in dirt, and generally got dirty. It was great, and our faces hurt from so much smiling.

The Eating
We came away with a bundle of the beauties ourselves, and have been eating and sharing them since. Stew, steamed, baked in a neighbor's oven, and in dessert (bought at the grocery), the sweet potato is on every table and part of nearly every course at the moment. I've included my version of this original recipe I found on Epicurious years ago. It's a sure crowd-pleaser, and it tastes good the moment it's made. The orange juice base makes it good for warding off colds, too.

Joan's Sweet Potato Stew
2 tablespoons olive oil
2 cups (or one whole medium to large onion) chopped a bit coarsely
2 tablespoons fresh minced ginger (without is ok, too, but it is a lovely addition)
1 1/2 teaspoons ground cumin
2-3 medium to largeish peeled sweet potatoes, cubed
4-6 cloves of garlic, minced
2-3 cups of orange juice
1 15 ounce can of black beans (2 is good, too) rinsed and drained

Heat the oil in the soup pan, throw in the onion, and cook covered until the onion is well-cooked and soft. I find the longer I cook it (without burning it) the better. Throw in the garlic, ginger, and cumin, and cover again. Toss in the cubed sweet potatoes, stir, and add the orange juice. I tend to add orange juice until the mixture is covered and the sweet potato bits are swimming a little. Then I throw in the beans, and let it simmer along until the sweet potatoes are done.

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
