Nikolai Blue – Earthy Clay (Edible Clay for Pica or Geophagia)

“Really thin, crisp layers with a loud crunch that melts down soft.”

Found near the Cheyenne River in South Dakota, Nikolai is a naturally layered chew with a beautiful, crisp crunch. When dry, it has a mild, clean mineral taste with subtle earthy notes and breaks apart into satisfying flaky layers (some pieces may be hard and need soaking). As you chew, it softens into a smooth, muddy texture that isn’t very sticky unless you eat a larger amount at once.

If you love Indian butter greys, you’ll recognise the way Nikolai breaks apart into flaky layers, though it isn’t waxy. The layers are really thin and crisp, giving a loud, really satisfying crunch before it melts down, with no grit.

This is one for texture lovers more than flavour chasers. The taste is a mild earthiness that’s only mildly muddy, nowhere near as pronounced as many other clays and dirts.

Dampen it, and the experience changes. It turns really soft, and the earthy flavour becomes richer and more noticeable, while keeping its signature layered texture.

Whether you enjoy it dry or damp, Nikolai offers two different experiences in one naturally layered clay.
