The website Blondie gave is a good forum.
Here are basic instructions on how to Pasteurize your milk. One thing they don't tell you is to strain the milk through a filter. A coffee filter will work.
Some people do this and some drink the milk raw, unpasteurized.
We plan to use ours raw when our Nubian nanny's have their kids in the Spring.
Pasteurizing Milk
If you don't have a store-bought pasteurizer, you can easily perform this task on your stovetop.
You can use the double-boiler method. If you don't have a standard double-boiler, just use two pots, one large and one smaller, so that the small one can fit into the large one. The reason you want to do this is so that the milk doesn't scald on the bottom.
Directions;
Put a few inches of water in the bottom half of the double-boiler. In the top pan, place your milk. Using a thermometer, heat the milk up to 161 degrees F slowly. Stir it to make sure the milk is an even temperature throughout.
After it is brought up to 161 degrees F, remove the top pan and set it in a sink full of very cold water to cool it quickly.
