Mushroom Čalamáda (Pickled Mushroom Relish)

Mushroom čalamáda is a traditional Czech and Central European pickled delicacy in which mushrooms, most commonly button mushrooms, oyster mushrooms or wild forest varieties, are preserved in a vinegar brine together with vegetables, spices and herbs. The result is a distinctly tangy, aromatic side dish with a firm texture. It is served as a cold accompaniment to meat, as part of a cold platter, or as a snack. Thanks to the brine, it has a vibrant, refreshing flavour and a long shelf life. It is made both at home and commercially, with recipes varying in spices, types of vegetables and the ratio of vinegar to sugar.
