Recipe Information
Ingredients
- 8 cups Whole milk
- 0.25 cups Plain yogurt with live active cultures
Instructions
Pour the whole milk into a large saucepan and place it over medium heat.
Heat the milk until it reaches 180°F, stirring frequently to prevent scorching. Use a food thermometer for accuracy.
Once the milk reaches 180°F, remove the saucepan from heat and let the milk cool to between 110°F and 115°F. This is the optimal temperature range for fermenting yogurt.
In a small bowl, mix 0.25 cups of plain yogurt with a bit of the cooled milk to temper it. Then, stir this mixture back into the cooled milk in the saucepan.
Pour the milk mixture into a clean container or jar with a lid.
Prepare your cooler by filling it with warm water (about 115°F). The water level should surround the jars but not submerge them.
Place the sealed container into the cooler and close the lid tightly to retain heat. Allow the yogurt to ferment for 6-10 hours, checking occasionally to ensure the water remains warm. If it cools, replace some of the water with fresh warm water.
After the fermentation period, remove the yogurt from the cooler and check for desired consistency. The yogurt should be thick and slightly tangy.
Transfer the yogurt to the refrigerator and chill for at least 2 hours before serving.
Store in the refrigerator for up to 7 days. Enjoy plain or with your favorite toppings like fruit, honey, or granola!
