Are you using milk raw? Why take the chance?
While it is true that some nutrients are detroyed to some extent during pasteurization it also makes milk much safer to drink. Remember that milk is one of the most nutritionally complete foods – not only for humans, but also for bacteria, fungi, molds, etc 😉
If you are buying raw milk and you want to make it safe without detroying a lot of nutrients, pasteurize at 65 degrees Celsius for 5 minutes.
This is easily done by placing a pot inside of another one and filling the gap in between with water and placing on the stove – -like you would when melting chocolate. The milk comes inside the centre pot with a thermometer. Afterwards cool in the sink – which should be filled with ice water.
Hope that helped,
