What is ryazhenka?

Ryazhenka is a traditional fermented dairy drink from Russia, Ukraine and Belarus. It is made from baked or slowly simmered milk that is then fermented with a culture, which gives it a caramel flavor and a pale beige or brownish color. One guide compares its taste to unsweetened yogurt.

How is ryazhenka made?

Methods differ, and sources differ on the order and the times, so treat these as typical outlines.

  • Traditional: milk (sometimes with cream) is heated in a clay pot until it turns beige, then sour cream is added and the milk ferments for roughly 3 to 6 hours.
  • Home oven method: one recipe uses fresh whole milk with about 1 tablespoon of sour cream or kefir per 2 cups, and bakes it at low heat for about 6 to 8 hours until a golden crust forms.
  • Slow cooker: the same recipe suggests low heat for about 8 to 10 hours with the lid slightly open.
  • Factory: producers use thermophilic streptococci and Lactobacillus bulgaricus, the same bacteria used in yogurt.

The browning comes from sugars and proteins reacting as water evaporates, which is also why it tastes of caramel.

What does it taste like?

Similar to unsweetened yogurt, with a caramel note and some sourness. The starter changes the result: sour cream gives a creamier, sweeter drink, kefir a sharper, grainier one.

How do you drink it?

Cold, on its own.
