The best way to defrost milk is to keep it in the fridge or place the container in some cold water. It’s safer to thaw it gradually, so expect the defrosting process to take about 1-2 days.Unfortunately, there are disadvantages to freezing and defrosting milk. When freezing and defrosting milk, the flavour and texture can change. However, its nutritional value does not. Therefore it’s better to use defrosted milk as a baking or cooking ingredient rather than served fresh, such as over breakfast cereal.Freezing milk can make it last for between 1-3 months. Once defrosted, it should be consumed within a couple of days.
