You use the freezer for many foods that you wouldn’t normally think of putting in the freezer: I keep cheese, milk, nuts, and sometimes tomato paste in mine.
You can freeze many hard or semi-hard cheeses, such as Cheddar, mozzarella, muenster, provolone, Swiss and Parmesan. They may become crumbly after you thaw them, so plan to use them in cooking rather than to slice or place on sandwiches. Wrap cheese tightly in plastic wrap and place in a freezer bag for up to 4 months. Thaw in the refrigerator and use within a day or two of thawing.
Unless you know you’ll use a whole container shortly after thawing, it’s best to freeze milk in smaller portions. One-cup or pint-size portions are convenient. Freeze milk in freezer-safe containers or in well-sealed freezer bags – but be sure to include some extra space, as milk expands when it freezes. Use the frozen milk within 1 month. Defrost in the refrigerator, and shake it well before using it. Milk sometimes becomes grainy after it’s been frozen and defrosted – if the texture is too unpleasant to use for drinking or on cereal, use the milk for cooking or baking.
Place nuts in an airtight container, or wrap them tightly in plastic and place in a freezer bag and freeze for up to 6 months. Thaw at room temperature or in the refrigerator – or, if using them for baking, toss them into a recipe frozen (though you may need to add a few minutes to your baking time).
Spoon tomato paste into an ice cube tray, freeze until solid, then transfer cubes to a freezer bag and freeze for up to 3 months. Be sure to measure how much you’re putting in each compartment (1 Tbsp. is a convenient amount) and label it on the freezer bag.
