This mushroom has several names: purple knight's cap, purple false knight's cap, and the French pied bleu is also widely used. The mushroom occurs in the wild. Mainly in France, this wild mushroom is picked in October and November. The young specimens are very tasty. The purple knight's cap has a sweetish smell and a strong flavor. When fried, the mushroom goes well with a game dish or in a pasta.
The name of this mushroom comes from its purple color, which is especially visible on the long stem. The stem is about eight to ten centimeters long, and the creamy-colored cap is large in size. Purple mold fluff can appear on the stem. This is related to the soil condition. When the soil is poor, this fluff develops. After harvest, the fluff continues to grow. This is not a problem, as the fluff is perfectly edible.
The purple knight's cap has a high dry matter content, which means it releases little moisture during frying. The flesh is firm, causing the cap to break easily. Do not clean the mushroom with water, but with a brush or cloth. In the refrigerator, it is about five days shelf-stable.
The purple knight's cap cannot be eaten raw! Fry the mushroom a little longer than usual.
