How can you pasteurize milk at home

This should take hours, depending on crock size and milk volume. I have never had scorched milk unless I use the high setting. I use medium heat, but that means I must pay close attention. Any higher and I accidentally burn the milk. Double Boiler : This follows the same concept as stovetop, but the extra water layer between pots keeps you from scorching the milk. If you have a double boiler, take advantage of it.

Small farms running dairy operations may want to consider one, though. Other options : The steamer feature of a cappuccino machine effectively pasteurizes milk if it brings temperatures above degrees F for over 15 seconds.

Some people have even used their sous vide water bath units to pasteurize, since those devices are designed to reach and hold a specific temperature for a specific amount of time. Just sticking the pot in a fridge or freezer sounds easy, but all that heat could raise the temperature and humidity in your fridge to unsafe levels. Steam condenses on freezer racks. I find the easiest way to chill milk fast is to put a lid on the pot, to avoid splashing water in the milk.

Part 1. Set up a double boiler. Fill a large pan with about 3 to 4 inches 7. Place a slightly smaller pan in the water, ideally without the bases touching. This setup lowers the risk of scorching and burnt flavors. Put a clean thermometer in the top pan. You'll want to track the temperature constantly, so a floating dairy thermometer or a clip-on candy thermometer works best. Wash the thermometer in hot, soapy water first, then rinse.

Ideally, sanitize the thermometer by rubbing it with a single-use alcohol swab, then rinsing again. If your thermometer doesn't clip to the pan or float, you'll have to insert it by hand frequently during pasteurization.

Work near a sink so you can clean and sanitize the thermometer again after every measurement. Prepare an ice bath. The faster you cool your milk after pasteurization, the safer and tastier it will be. Fill a sink or large tub with cold water and ice so you'll be ready to go.

An old-fashioned ice cream machine is especially effective. Pack the outer compartment in ice and rock salt as you would normally. After reading, you might decide to use the longer pasteurization process, in which case you'll want to keep the ice in the freezer for another half hour. Part 2. Pour the raw milk into the inner pan. Pour through a strainer if the milk hasn't been strained since it left the animal.

Heat while stirring. Place the double boiler over medium—high heat. Stir frequently to help equalize the temperature and prevent scorching. Watch the temperature closely. Make sure the thermometer probe is not touching the sides or base of the pot, or the measurement will be off. As the milk approaches the temperature listed below, stir constantly and draw milk from the bottom of the pan to eliminate hot and cold spots.

Keep it at or above this temperature for 15 seconds. Remove from heat immediately. Keep the milk at or just above this temperature for 30 minutes. Remove from heat. Cool the milk rapidly in the ice bath. The faster you cool the milk, the better it will taste. Put it in the ice bath and stir frequently to help release heat. After a few minutes, replace some of the warming water with cold water or ice.

Repeat this whenever the water warms — the more often, the better. This can take as long as forty minutes in an ice bath, or twenty minutes in an ice cream machine. Pasteurize it again and cool it more rapidly. This information may be printed and distributed without permission for non-profit, education purposes.
