About Acorn

An acorn is the nut-like seed of an oak tree, used as food in some culinary traditions after suitable processing. Because raw acorns can be strongly bitter, edible preparations commonly involve removing tannins, then cooking or drying the kernels.

The kernel is enclosed in a hard shell and has a firm, starchy texture when prepared. Its flavour can be mild to nutty after processing, but varies among oak types and preparation methods. Acorns may be eaten whole, ground into meal, or processed into flour.
