Ginnan

Ginnan are Japanese gingko seeds characterized by a pungent smell, soft and sticky texture, and a slightly bitter flavor. They also act as cough suppressants and are highly nutritious. Ginkgo trees can be found throughout Japan and China, and the seeds are usually collected in Autumn, when they fall to the ground.

Although it is not that common to consume them, they are sometimes roasted or used in the preparation of a savory egg pudding known as chawanmushi. One should be careful when consuming ginnan, because it can cause poisoning by MPN if eaten in large quantities (more than five seeds per day).
