Ryazhenka (say: rye-AH-zhen-ka) is a special kind of fermented milk product that's popular in Ukraine and Russia. It's made from milk that has been baked, then fermented with good bacteria. This process gives it a unique creamy color and a slightly sweet, caramel-like taste. It's a traditional drink often enjoyed on its own or used in cooking.

What is Ryazhenka?
Ryazhenka is a dairy product that's a bit like yogurt, but it has a different flavor and texture. It's made by taking milk and heating it for a long time until it turns a creamy color. Then, special good bacteria are added to make it ferment. This fermentation process makes the milk thicker and gives it a slightly sour, yet sweet, taste.
Where Did Ryazhenka Come From?
Many people believe that Ryazhenka started in Ukraine. In older books from Russia and the Soviet Union, it was often called "Ukrainian Ryazhenka" or "Ukrainian soured milk." The name "Ryazhenka" itself is connected to a Ukrainian word, "pryazhene moloko," which means "baked milk."
There are similar drinks in other countries too! For example, in Russia, there's a product called varenets that's also made from baked milk. While they are very similar, they have slightly different ways of being made in factories. Other similar products include qatiq and kaymak from Turkic countries. The main thing that makes these drinks special is that the milk is heated to a very high temperature before it's fermented.
How is Ryazhenka Made?
Making Ryazhenka takes a bit of time and a special process.
Baking the Milk
First, the milk is heated to a very high temperature. This is called pasteurizing it, which kills any bad germs. After that, the milk is simmered (cooked slowly at a low heat) for at least eight hours.
In the past, people would put a clay pot of milk into a traditional Ukrainian oven. They would leave it there all day until a brown crust formed on top. This long heating process causes a special chemical reaction called the Maillard reaction. This reaction happens between the milk's proteins and sugars, creating new compounds called melanoidins. These are what give Ryazhenka its creamy color and delicious caramel flavor. A lot of the water in the milk also evaporates, making it thicker.
Fermenting the Milk
After the milk is baked and cooled a bit, it's time for fermentation. If you're making it at home, you might add a spoonful of sour cream (called smetana) to start the process. This sour cream contains the good bacteria needed for fermentation.
In factories, special types of bacteria are used, mainly Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. These are the same kinds of bacteria often found in yogurt! The milk mixture is then kept in a warm place, usually around 40°C (100°F). The bacteria get to work, and the fermentation usually takes about three to six hours.
What's Inside Ryazhenka?
Ryazhenka is a healthy drink! The amount of fat in Ryazhenka made in factories is usually between 3.5% and 4%. However, it can be made with less fat (from skimmed milk) or even more, up to 8.9%. It has at least 3% protein, which is good for your muscles, and usually 4-5% carbohydrates, which give you energy. Because the milk is heated so much, Ryazhenka is safe to store at room temperature for up to 40 hours.
