Blini are thin, round pancakes that originate from Eastern European cuisine, particularly popular in Russia and Ukraine. They are traditionally made from a batter of flour, eggs, milk, and yeast, which gives them a light and fluffy texture. Blini can be served in various sizes, from small bite-sized pieces to larger pancakes. These versatile pancakes can be enjoyed in both sweet and savory forms. Common toppings include sour cream, caviar, or smoked salmon for savory options, while sweet variations may feature jam, honey, or fruit. Blini are often served during celebrations, including Maslenitsa, a festival marking the end of winter.
