Blinis are small, thick pancakes that are a traditional food in Russian and other Eastern European cuisines. They are made with a batter that typically includes flour, eggs, milk, and yeast or baking powder, which gives them a light and fluffy texture. Blinis are often served as an appetizer or a snack, and are typically topped with savory or sweet ingredients, such as smoked salmon, caviar, sour cream, jam, or honey.
