To Pasteurize Milk

Ingredients

• milk
• water
• ice

Directions

1. Set the bottles of milk in a pail with a perforated false bottom or an inverted perforated pie tin.

2. Insert a thermometer into one of the bottles by punching a hole in the cap or through the cotton plug.

3. Fill the pail with water nearly to the level of the milk.

4. Heat the water until the thermometer registers 150°F (65°C).

5. Change the thermometer from the milk to the water, adding cold water until the water temperature is also 150°F (65°C).

6. Cover the kettle and maintain this temperature for 30 minutes.

7. Cool the bottles by running water into the pail.

8. Remove the bottles and place them immediately on ice.

9. If no thermometer is available, boil 1 gallon (4 quarts) of water in a kettle with a perforated false bottom.

10. After boiling, remove the kettle from the stove and let it stand uncovered for 10 minutes.

11. Put the filled and loosely corked bottles into the water, cover the kettle, and let it stand covered for 30 minutes.

12. Remove the bottles, cool rapidly under running water, and place in the ice box until needed.

13. Do not uncork the bottle until it is time to feed the baby.
