In the video, a person is seen pouring milk into a pot of cocoa powder. The person then uses a whisk to stir the mixture. As the milk is added, the cocoa powder begins to dissolve and mix with the milk, creating a smooth and creamy consistency. The person continues to stir the mixture, ensuring that all of the cocoa powder is fully incorporated into the milk. The final result is a rich and creamy chocolate mixture that is ready to be used in a variety of recipes.
