The video shows a close-up of a wooden cutting board with sliced mushrooms on it. The mushrooms are coated with a white powdery substance, which appears to be flour. A person's hand is seen sprinkling the flour over the mushrooms, ensuring that they are evenly coated. The mushrooms are dark brown with white stems, and the flour is being applied from above, creating a contrast against the dark color of the mushrooms. The hand moves methodically from one mushroom to the next, ensuring that all pieces are coated.
