Storing and freezing eggsEggs should always be stored in a cool, dry place, ideally in the fridge. However,
you will often need to remove eggs from the fridge a little before cooking time
to bring them to room temperature. This is particularly important when boiling eggs,
as they can have a tendency to crack when going into simmering water if they are too cold.
Store eggs apart from other foods, especially strong smelling foods because egg shells
are porous. If you have an egg tray in your fridge, this is the ideal place to store them,
otherwise keep them in their boxes. The exception to this rule is if you're lucky enough
to be in possession of a fresh truffle. By storing it in the box with the eggs for a few days
the eggs will take on some the truffle's flavour. You can then use the eggs for luxurious
scrambled eggs.
Eggs can be frozen, but you'll need to crack them first. To freeze whole eggs, break them
into a bowl and beat a little to blend. Tip into a freezer bag or airtight plastic container,
label the container and use within three months.
If you're separating eggs for particular recipes, you'll often end up with a surplus of yolk
or white. These can be frozen to be used another time. It's best to freeze them in small
batches, as these will be most useful. Be sure to label the number of eggs that go into
each freezer bag.
Egg whites can simply be tipped into freezer bags and labelled, whereas egg yolks need
a pinch of salt or sugar beaten in (depending on whether they'll be used for sweet or
savoury dishes later). This will stop the yolks becoming too thick with freezing. Defrost
frozen eggs in the fridge overnight and use them straightaway.
Never use eggs after their 'Best Before' date and never use eggs with damaged shells. Eat
dishes containing eggs as soon as possible after preparing them. Otherwise, cool them
quickly and store them in the fridge.
