Tear rather than cut, fry hard so the edges crisp. Do not stew to mush.

Recipes using Oyster Mushroom

  • Wild Mushrooms on Toast

    The honest test of any wild mushroom. Butter, a hot pan, good bread and nothing to hide behind.

  • Rich wild woodland mushroom soup

    A thick, dark, thoroughly old-fashioned soup thickened with stale bread rather than flour. It was written for a big autumn haul of mixed woodland mushrooms and it is still the best way to use a basket of odds and ends.
