Samedi 16 novembre | Asako Kitaori & Dion Workman | Walking on Boundaries
FOR THE TIME BEING Yesterday it was summer hot but today the air has a distinctly winter chill. In this warm temperate climate we do not get the archetypal colors of autumn, the mountains, lacking fiery reds and oranges turn a more muted yellow brown. This is the time when the forest is most bountiful. Every rain draws mature walnuts to the ground. Some for us, some for the squirrels, some for the wild boars. And some staying on the ground to become the next generation of walnut trees. Where ever we walk there are acorns scattered over the forest floor in a wide variety of shapes and colors. Their tan to dark brown coloring camouflages them well against the leaf litter causing us to walk stooped, eyes fixed on the ground beneath our feet as we try to spot the more desirable species. Long before humans were farming grains—and in many places for a long time afterwards too —acorns were an important food source. In Japan the Jomōn hunter/gatherers would collect acorns, leach the bitter and astringent principles by soaking the shelled and crushed acorns in running water, then grind them up to make cookies or a dish resembling the modern hamburger. We are fortunate to have many trees of sudajii which produce an acorn free of the tannins that produce the astringency in other species. Although we are also experimenting with leaching tannins from other acorns, trying to determine which species are best for making flour. Akebi, whose tender young shoots we eat in spring, now dangles clusters of oblong purple fruits from high in the trees. A split in the skin tells us they are ready, an invitation to taste the sweet pulp contained within. We harvest what we can reach from the vines as they climb to the canopy, the birds and monkeys getting those beyond our reach. Fruit trees employ different tactics from nut trees: moving seeds far from the mother tree by enticing animals to feed on their fruits and deposit the undigested seeds throughout the forest as they roam. Nut trees on the other hand drop large quantities of seed directly below the parent, encasing the seed in hard shells that can roll or float without damage (or to be stashed away and sometimes forgotten by squirrels). Another fruit we are enjoying now is persimmon. Mostly we have astringent varieties around here; unpleasant when firm, when soft and ripe the fruit is much sweeter than the so-called sweet persimmon. Perhaps the astringency of the firm fruit is a tactic for protecting the seeds until they are fully mature. This seems to work to keep away the birds and 'lower' primates; however that clever monkey the human has found a way to rid the young fruits of their tannins and hence their astringency. Traditionally in Japan people pick still hard fruits which they peel and hang in the sun for about a month, regularly massaging the fruits to soften them as they dry. The end product is like yōkan, a dense jelly-like Japanese sweet. These extraordinarily sweet whole dried persimmons—now with all trace of astringency gone—literally melt in the mouth. This long tradition which sees house fronts festooned with bright orange persimmons strung together like Halloween decorations (strings of orange shrunken heads) will likely disappear with the changing climate. For the operation relies on the synchronization of the persimmon harvest with cold winter winds, allowing for a long drying time without the fruits becoming moldy. An occurrence once taken for granted, reliable as the changing seasons, it now occurs with much less frequency. Clever monkey indeed. Cool damp days of autumn and spring are usually what is needed to spur the fruiting of shiitake mushrooms. This year they received a lashing from a late typhoon; drenched for hours by pouring rain driven sideways by gusting winds. They respond favorably to a bit of rough treatment (soaking inoculated logs and knocking them around is a trick long employed by shiitake growers to encourage a flush of mushrooms.) The typhoon triggered a good first flush of shiitake, enough to fill a couple of baskets. Elsewhere funny-shaped mushrooms have popped up on the ground and on decomposing wood. The oysters, puffballs and kikurage ('wood jellyfish', named for its blubbery texture resembling jellyfish) we harvest to eat, many of the others, strange and intriguing, we admire with caution. Mushrooms growing on cut or fallen logs are the 'teeth of the forest,' the first stage in the consumption of organic matter that feeds the vast soil ecosystems underground which in turn feed the herbs and mighty trees above which in turn feed us animals. Though they seem to arrive suddenly from nowhere the mushrooms are actually the 'fruits' of fungal networks (mycelium) running through the downed logs and just below the soil surface, sometimes covering huge areas of land. Other mycelium serve as communication networks for the forest. Plants suffering insect damage in one section of the forest will send chemical messages via the mycelial networks to susceptible plants in other parts of the forest; a sort of early warning system encouraging the release of chemical defenses before the attackers arrive. If one area is lacking certain nutrients, the required nutrients may be transported via the mycelial networks to the plants in need. This is no underground Internet but rather a complex anatomical system, alive and functioning as a whole. When we dig or plow the soil we cut through these thread-like delicate networks like severing nerves and arteries. This year in a place not far from here, we are told, the cherry trees are blossoming now, in autumn. Perhaps Japan's best known seasonal celebration is the hanami or flower viewing festivals. When the cherry trees blossom in spring families and friends take blankets to the park or countryside to sit under the cherry blossoms, drinking sake and eating together. Of course, if their blossoming was merely for the occasion of the hanami it would be a simple matter of rescheduling the picnic.
