In the Slovak, Ukrainian, Carpatho-Rusyn Orthodox Christian tradition, sour mushroom soup (machanka or mačanka) is a meatless soup served for Christmas Eve velija supper and also any time fasting is required, like Advent and Lent.

It's a hearty soup made with woodsy dried mushrooms that must be reconstituted by soaking overnight, so plan accordingly.

Temper the mixture of 1/2 cup flour and 1 cup water by adding a little hot soup into it, whisking until smooth.

Recipe Variations

  • For Christmas Eve, the soup course for Slovaks who are Catholics typically is kapustnica, a sauerkraut soup with mushrooms, garlic, caraway, paprika, nutmeg, onions and apples or plums for a hint of sweetness. When the soup is served on a non-fasting day, pork and sausage are added to the cooking pot.
  • In the eastern part of Slovakia, it is called jucha and is made only from sauerkraut juice mixed with dried peas, plums and, on nonfasting days, can include sausage. Where the cuisine has been influenced by the Orthodox Christian tradition of Ukraine, it is known as mačanka (also spelled machanka) as in the above recipe.
