Dinosaur Food: 100 million year old foods we still eat today (borischerny.com)

I just finished Oliver Sacks’ excellent Everything in Its Place. In it, he mentioned as an aside that the Ginkgo biloba tree is hundreds of millions of years old, and its phenotype has been practically frozen since then – a living fossil.

Of course, this is the same tree that grows ぎんなん (Ginkgo nuts), an East Asian delicacy found in many dishes, 茶碗蒸し (Chawanmushi) for example.

Ginkgo has been around so long, it predates the dinosaurs! And we still eat it! How cool is that. This got me thinking – what are the oldest foods we consume today?

Criteria:

Must be edible by humans

Must be morphologically unchanged since its fossil age

Araucaria araucana Monkey puzzle tree nuts

There's also Araucaria angustifolia (aka Paraná pine). Dunno if it counts as either a separated entry or same entry as the A. araucana, both are phylogenetically close to hybridise, and the genus as a whole is what's dino food.

Some pics:

(Yup, it's my cover picture. See the big tree?)

(Open and closed pines, full of edible nuts.)

(Pine kernels with and without the shell.)

I go crazy for those once May* hits — they're delicious even simply boiled, but they can be also prepared into dishes. (I even adapted Roman burgers to use those.)

*They actually start producing in April, but as there's a non-zero chance the pine nuts from April are from felled trees, I avoid it. The species is critically endangered; eating some nuts is not a big deal, but falling the tree is.

Good to know! I'd hate for these to suddenly become a fad and then endanger the tree even more. Knowing about the issue ahead of time means that people might check for it when buying it
