- ½ gallon milk
- ½ c. powdered milk if using 2% or non-fat milk
- ½ c. plain yogurt with active cultures
- In large crockpot, add ½ gallon milk and turn on low for ~1-2 hours, until 180*F.
- Remove lid and cool down until 115*F. This temp should be accurate within 5*F to not kill the yogurt culture.
