Blinis are small, round pancakes that originate from Eastern Europe, particularly popular in Russia. They are traditionally made from a batter of flour, milk, eggs, and yeast, resulting in a light and fluffy texture. Blinis can be served warm or cold and are often enjoyed during celebrations and festivals. These pancakes are versatile and can be topped with a variety of ingredients, such as caviar, sour cream, or smoked salmon. Blinis are commonly served as appetizers or snacks and are a staple in Russian cuisine, often accompanying dishes during special occasions like Maslenitsa, a festival celebrating the end of winter.
