One must have at the Christmas dinner tables in Poland is herring. There are multiple varieties of traditional Christmas herring, including mustard herring, sour cream herring, or Kashubian-style herring. Kashubian-style herring originated in the Kashubian region of north Poland but is also very popular in other parts of this country. The fermented herring is mixed with tomato sauce, aromatics, and raisins or prunes. It can be prepared in advance, a day or two before Christmas because it will develop the flavor with time.
In this recipe, we recreated beloved Christmas’ herring using fermented shaggy inkcap mushrooms. We chose shaggy inkcap mushrooms because they have a herring-like shape and because they grow in the late fall-early winter season. You can find more about the fermentation of this kind of mushroom here.
