In the video, a person is pouring a carton of milk into a glass baking dish. The dish is filled with sliced onions that are arranged in a circular pattern. The milk is being poured from a height, causing it to splash slightly as it hits the onions. The person's hand is visible as they hold the carton, and the background appears to be a kitchen counter. The milk is white, and the onions are a pale yellow color. The glass baking dish is clear, and the milk fills up the spaces between the onion slices.
