1. Heat the milk in a pot over medium heat. Stir frequently until the milk reaches 37-43°C / 100-110°F.
8 Cups Whole Milk
2. Temper the yogurt by gradually adding 1 cup of milk, stirring constantly. Mix with the remaining milk once the yogurt is smooth and stir until combined.
1 Cup Plain Yogurt
3. Transfer the milk to a jar or container and wrap it with a tea towel; this will help keep the milk warm. Let it sit in a warm place (100 - 110°F / 37 - 43°C) for 4 to 8 hours, or until it has thickened. I leave mine inside the oven turned off with the light on.
4. Line a strainer with cheesecloth and place it over a bowl. Allow the yogurt to strain in the fridge for at least 3 hours or until it reaches the desired consistency. I usually leave it overnight.
5. After straining yogurt, you will get a byproduct called whey. Whey is an excellent addition to bread recipes, adding protein and flavor.
Enjoy!
