Homemade yogurt is easy to make with just milk and yogurt.
This helps create a thicker yogurt. If heating on stove, stirring prevents milk from boiling over. In a slow cooker, don’t stir it because that keeps the milk from heating up. Expect that heating the milk may take a couple of hours or more. A thermometer is the only way to be accurate.
Save some yogurt to use as the starter for the next batch of yogurt.
