In the video, we see a person's hand spreading a white sauce onto a tortilla. The tortilla is placed on a white paper towel, and the sauce is spread evenly across the surface. The person's hand moves in a circular motion, ensuring that the sauce covers the entire tortilla. The sauce appears to be creamy and thick, and the tortilla is a light brown color. The person's hand is visible in the frame, and we can see the motion of the hand as it spreads the sauce.
