In New York Metropolis, there are avenue tree seasons that odor superb—like early summer season, when lindens are in bloom. And there are seasons that may odor very, very unhealthy: Fall, and ginkgo timber dropping fruit. And that is true wherever feminine ginkgo timber develop. These historical timber, among the oldest organisms on earth, had been the familiars of dinosaurs, which they outlasted. They’re distinctive in a number of methods, and the stench of their damaged, autumn-ripe fruit is only one of their mysteries (for whom was the putrid odor an irresistible name to feast?). Inside their yellow pulp, protected inside a pistachio-like shell, is their scrumptious, sought-after kernel, a useful meals in East Asia for millennia.
Getting ready ginkgo fruit to eat will not be half as difficult as it could appear.

Freshly-cooked ginkgo kernels (they don’t seem to be technically nuts) are scrumptious—tasting one thing like a hybrid of chestnut, pine nuts, and tofu—and they’re completely odor-free. Ginkgo is often eaten in China, Korea, and Japan.
My very own ginkgo adventures started comparatively late in my foraging life, within the autumn of 2018. Emboldened by the Asian ladies I noticed gathering fallen fruit beneath feminine timber in Brooklyn’s Prospect Park each fall, I shyly adopted their instance, scooping the ripe fruit up rigorously in gloved fingers. They wore plastic baggage on their toes, to guard their sneakers from the reeking pulp. (Unbroken fruit doesn’t odor). Again dwelling, after cleansing, boiling, and roasting them, I tasted my first, contemporary, vividly inexperienced ginkgo “nut,” It was love at first chunk.
Ginkgo timber are uncommon within the wild (and so they reside in China). However there are lots scattered in cities across the globe, planted in areas with chilly winters and humid summers. The timber are resilient, pest-free, and exquisite. For decorative functions, male timber are most popular, since they kind no smelly fruit. However females timber do sneak in, and that’s very fortunate for city dwellers who recognize the bounty when it falls in mid-autumn.
For plant geeks: Ginkgo biloba is the one species within the genus Ginkgo. That genus is the one one within the household Ginkgoaceae, which is the one occupant of the order Ginkgoales, which is the only member of the division Ginkgophyta. The fossil report of ginkgo is over 200 million years outdated.
Ginkgo fruit does include toxins: Within the uncooked pulp there’s urushiol (suppose poison ivy) which might trigger contact dermatitis. Sporting gloves is essential when dealing with any damaged fruit or when eradicating the kernel. (Curiously, the raccoons and possums who relish metropolis ginkgo—consuming the smelly pulp solely—don’t know in regards to the glove-rule and appear to be simply effective.)
The kernel of ginkgo comprises cyanogenic glycosides, that are heat-sensitive, and are destroyed by cooking. There’s additionally so-called ginkgotoxin, a neurotoxin that’s not heat-sensitive; it inhibits the absorbtion of Vitamin B6, which is important for nervous system growth. In a case of overdose the kernels may cause sickness and even seizures. In accordance with the authors of a 2020 paper documenting a single case of “presumed” ginkgo poisoning case in Japan, “seven to 150 items for youngsters and 40 to 300 items for adults are the ranges for overdose.” That’s very broad! (The individual in query ate round 80, for those who’re curious, and was additionally described as actively alcoholic). A Japanese buddy who has eaten ginkgo all her life—she is in her 70s—cuts herself off at 12. And I’ve eaten 20 with no in poor health impact, however my standard dose is about six, as snack on a skewer. It takes monumental self-restraint.
