Butter: If you get a good deal on butter but couldn’t possibly use it up before its best before date, you can certainly stash it, still wrapped, in your freezer for up to 12 months. Flavoured and compound butters can also be frozen when tightly wrapped.
Cheese: Wrap hard cheeses (like cheddar, Parmesan) tightly in plastic and they’ll keep for up to 6 months. You can also shred hard cheese, freeze it, store it in an airtight container and use it from frozen. Soft cheeses like goat, ricotta or cream cheese won’t freeze well, as there’s too much moisture in them.
Eggs: Don’t try to freeze eggs in their shells – they’ll explode! Instead, crack them into muffin tins, lightly beat them with the tines of a fork, and freeze. Once frozen solid, pop the eggs out and place in freezer bag for up to 6 months.
