Autumn Ingredient: Ginkgo Nut
The ginkgo represents the autumn taste. Unfortunately, in the United State we do not see a lot of fresh ginkgo nut in the markets. You can often find them, though, in pills in the supplement section. When I see ginkgo nut in an Asian market, I buy a lot and freeze them so that I can enjoy them throughout the year. You can also find ginkgo nut in a can, but the flavor of the fresh nut is so much better.
The flavor of ginkgo nuts is bitter and medicinal. Yet, I truly love them! My memory of ginkgo nuts goes back to my childhood. My mother and I went to Nara Park to pick ginkgo nuts in the fall. The smell of the orange ginkgo fruit is very strong and unpleasant. The fruit can cause an allergic reaction such as a rash because of the butanoic acid in the outer flesh layer, so we picked the nuts using plastic bags in our hands to avoid touching the ginkgo fruit. We used our shoes to break the soft and stinky orange fruit first, and then we took out the hard-shelled nut. Beautiful gold colored ginkgo leaves covered the ground. The fall sunshine landed softly and caused more leaves to glow with the golden yellow hue. We were looking down and picking nuts. It was so beautiful and calm. Now, surprisingly, the stinkiness of ginkgo nuts is an appetizing smell to me.
The Ginkgo is a living fossil, which dates to as far back as 270 million years ago. It is an unusual plant with separate sexes, female and male. Male plants produce small pollen cones in spring and fly a range of 1 km to pollinate the female plant, which does not produce cones. Instead, the female plant forms two ovules at the end of a stalk. After the pollination or fertilization, these become seeds. The Japanese botanist, Sakogoro Hirase, discovered the male ginkgo sperm in 1896. The seed is 1.5-2 cm long and orange-colored. This orange outer layer contains butanoic acid and smells like feces once it falls off the tree. The ginkgo nut has a soft and fruit-like outer layer and a football-shaped hard-shelled nut inside. Inside the brown, thin-skinned shell is a milky green ginkgo nut, which turns jade-colored when cooked.
The ginkgo tree grows to between 66 and 115 feet high. The unique fan shaped leaves are 2 to 4 inches wide and 6 inches long. In spring, the leaves are bright green, in summer they become a darker green and in fall they turn golden yellow.
The ginkgo tree contains oil and grows straight which makes it a great resource for furniture, Igo/Shogi tables and cutting boards.

When I get fresh ginkgo nuts, I toast them in a sauté pan with no oil, until the thin brown skin peels easily and the nuts are translucent jade in color. Skewer 3 ginkgo nuts on a bamboo stick and sprinkle with sea salt. Goes great with beer, sake and shochu!
