If you have ever found yourself pouring a half-full carton of milk down the drain because it reached its expiration date, you are not alone. Many families find it difficult to guess exactly how much milk they will need each week. Sometimes a gallon disappears in two days, and other times it sits untouched until it spoils. Fortunately, there is a very easy way to stop this waste and save money: “you can actually freeze milk.”
How to Prepare Your Milk for the Freezer
Freezing milk is a simple process, but you must follow one specific rule to prevent a mess. Because liquids expand when they turn into ice, a full container of milk will grow in size once it is frozen. If the jug is completely full, the pressure will cause the plastic to split or the cap to pop off.
To avoid a “frozen spill,” make sure to pour out about one cup of milk from the container before you put it in the freezer. This gives the liquid enough room to expand safely. Additionally, always stick to plastic containers. Avoid using glass bottles, as the cold temperatures and the pressure from the expanding milk can cause the glass to “crack or shatter.”
Smart Storage Ideas
You can choose how to store your milk based on how you plan to use it later:
- Whole Containers: If you want milk for cereal or drinking, freezing it right in the original plastic jug is the easiest method.
- Milk Cubes: For those who only need small amounts at a time, try using an ice cube tray. Pour the milk into the tray and freeze it until the blocks are solid. These “perfectly portioned blocks” are great for adding to a hot cup of coffee, blending into a morning smoothie, or using in a recipe that only calls for a little bit of dairy. Once frozen, move the cubes into a freezer bag to keep them fresh and save room.
