Heat Milk to 185°F
You want the milk to reach 185°F to prepare the milk proteins for yogurt culture production. If you do not have a thermometer, this is also the temperature at which milk begins to froth, like in a latte.
- Keep water boiling
- Stir frequently
- If you hold the milk at 185°F for 30 minutes, you will get a very thick consistency.
- While you are waiting for the milk to reach 185°F, fill your sink about 1/4 of the way with cold water.
- Add some ice to the water.
