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.
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.
