Bliny are traditional Russian pancakes made from a batter of flour, eggs, milk, and yeast or baking powder. They are typically thin and can be served in various ways, either sweet or savory. Common fillings include jam, sour cream, or caviar, making them a versatile dish enjoyed at any meal. These pancakes are often associated with Maslenitsa, a week-long festival celebrating the end of winter. During this time, people eat bliny to symbolize the sun and the arrival of spring. Bliny can also be found in other Slavic cuisines, showcasing their popularity across different cultures.
