How to ID it

Smooth, grey "elephant-skin" bark; often holds tan dead leaves through winter
Small triangular nuts, two per soft-spiny four-part husk
Leaves oval, glossy, with straight parallel veins ending in fine teeth
Crops vary wildly year to year — big "mast" years then near-nothing

Safety

Pleasant and safe in small amounts raw; for a quantity, roast them — raw beechnuts contain saponins and fagin that can upset the stomach if you eat more than a handful, and roasting neutralises them.
Rub off the thin skin over the kernel — it's bitter and tannic.

Harvest

Beech only crops heavily in periodic mast years, so some autumns there’s a feast and others almost nothing. When husks litter the ground and split open, gather them — the little triangular nuts hide two to a husk. Skip flat, empty husks; a lot of nuts don’t fill.

Prep

Open the soft-spiny husks and shell the nuts — fiddly work for the small reward. Rub off the bitter skin. Eat raw only a small handful at a time; to eat more, roast them, which drives off the fagin/saponins and brings out a sweet, mild flavor. Roasted beechnuts are also a classic coffee substitute when ground.

Notes

Patience is the whole game here: fill quality is low and shelling is tedious, but a good mast year is worth grabbing.
