To make yogurt using a Kitchenaid mixer, start by heating milk in a pot until it reaches 180°F. Then, let the milk cool down to 110°F and add a yogurt culture (either a store-bought yogurt or a previous batch of homemade yogurt) to the milk. Stir well, transfer the mixture to a container, and set the container in the mixing bowl of the Kitchenaid mixer. Fill the bowl with hot water to maintain a consistent temperature of 110°F, and cover the bowl with a towel. Let the mixture sit for 6-12 hours to allow the yogurt to form. Once the yogurt has set, remove the container from the mixing bowl, cool in the refrigerator, and enjoy!
