Homemade yogurt might sound daunting, but in fact it’s incredibly easy to make. This recipe for how to make homemade yogurt has two ingredients and is as easy as heating milk, cooling it, whisking in some ready-made yogurt, and then setting it aside for a night. Yes! It’s really that simple. Plus you can choose whether you want classic plain yogurt or a strained, Greek-style. Make sure you have an instant-read or candy thermometer, since accurate temperature is a key ingredient in making your own yogurt. As for the other key ingredient, dairy, look for milk and yogurt sourced from grass-fed cows that have never been treated with hormones or antibiotics. The reason you use premade yogurt in creating your own is because it contains good-for-you bacteria that will culture and ferment the milk. Once you’ve made your own there’s no need to buy more yogurt to start another batch—just use ¼ cup of your homemade one to get the next going.
