Selecting the right container is crucial when it comes to freezing milk. Airtight containers or freezer bags are the preferred choices as they prevent contamination and help maintain the quality of the milk. It's important to ensure that the containers are specifically designed for freezer use, as they can withstand the low temperatures without cracking or leaking.
When using airtight containers, make sure to leave some headspace at the top to allow for expansion as the milk freezes. This will prevent the container from bursting or the milk from spilling over. If using freezer bags, it's a good idea to double-bag them for extra protection against leaks. Lay the bags flat in the freezer to save space and ensure even freezing.
It's also worth noting that the material of the container can affect the taste and quality of the milk. Glass or BPA-free plastic containers are good options as they don't impart any flavors or chemicals into the milk. Avoid using metal containers, as they can cause the milk to take on a metallic taste.
In terms of thawing, it's best to do so in the refrigerator overnight to ensure that the milk thaws evenly and doesn't spoil. If you're in a hurry, you can thaw the milk in cold water, but be sure to use it immediately after thawing. Never thaw frozen milk at room temperature or in hot water, as this can cause bacterial growth and spoilage.
By following these guidelines for container selection and thawing, you can ensure that your frozen milk remains safe, fresh, and delicious for use in all your favorite recipes.

Quality Changes: Freezing milk can alter its texture and taste, potentially making it less desirable for drinking but suitable for cooking
Freezing milk can indeed alter its texture and taste, which may make it less appealing for drinking but still suitable for cooking. When milk is frozen, the water content forms ice crystals, which can disrupt the structure of the milk proteins and fats. This disruption can lead to a grainy or icy texture upon thawing, which might not be ideal for drinking milk. However, this change in texture does not necessarily affect the milk's suitability for cooking. In fact, many recipes, such as soups, sauces, and baked goods, can benefit from the use of frozen milk, as it can add a rich, creamy flavor without the need for additional fats or oils.
One important consideration when using frozen milk for cooking is to ensure that it is properly thawed before use. Thawing frozen milk in the refrigerator overnight is the safest method, as it allows the milk to reach a consistent temperature without the risk of bacterial growth. If you need to thaw milk more quickly, you can place the frozen container in a bowl of cold water, changing the water every 30 minutes until the milk is thawed. It's crucial to avoid thawing milk at room temperature or using hot water, as this can promote the growth of harmful bacteria.
Another factor to keep in mind is the potential for frozen milk to separate upon thawing. This separation occurs when the ice crystals that form during freezing disrupt the emulsion of fat and water in the milk. While this separation can be undesirable for drinking milk, it can actually be beneficial for cooking, as it allows you to easily remove the excess fat from the milk before using it in a recipe. To remove the separated fat, simply pour the thawed milk into a container and let it sit for a few minutes.
