Pour milk into an ice cube tray. Do not freeze milk when it is near or past its best by date.
Place trays into the freezer and allow milk to freeze.
Transfer frozen milk cubes to zip top freezer bag marked with the date. Use within 6 months.
To defrost milk cubes, place them in a covered bowl in the refrigerator.
Standard ice cubes are 1-ounce (2 tablespoons). Defrost 8 ice cubes for 1 cup of milk. If necessary, whisk or stir the milk if it separates as it defrosts
How to Freeze Milk in the Carton
Pour about 1 inch of milk out of the carton.
Mark today's date on the carton.
Freeze.
To defrost, place the carton on a plate in the refrigerator overnight. The plate will catch any condensation.
Once the milk is defrosted, make sure the lid is still on tight and then shake the living tar out of it. This will help the smoothness.
