Whether as a fried egg or a cake ingredient: eggs are among the most popular foods. How many days can eggs keep? How long does a breakfast egg cook? And how do I avoid them bursting while cooking?

It is important to always pay attention to the shelf life when processing eggs. This applies in particular to all dishes that contain raw eggs, such as tiramisu, pudding or homemade mayonnaise. These dishes should always be freshly prepared and, if possible, eaten on the same day.

Save and freeze leftover egg whites and yolks

Eggs are an important ingredient in a wide variety of dishes.

Remnants of egg whites and yolks, such as those left over when blowing out eggs for Easter decorations, last a little longer. Covered in a bowl in the refrigerator, both can be stored for about two to three days. If you want, you can freeze both. Add a little salt or sugar to the mixture. In the freezer at minus 18 degrees, an egg without its shell can be kept for six to ten months. If you only have protein left, you can freeze it without adding salt or sugar. It can be frozen for up to a year.

Best before: How long can eggs be used?

When buying eggs, it is advisable to always pay attention to the best-before date. It ends 28 days after the laying date. After that, the eggs are not bad if stored correctly. However, they should only be used for cooking or baking. It is important that they are heated to a temperature of over 70 degrees in order to kill possible germs such as salmonella.

It is best to store raw eggs in the refrigerator door

It is best to store raw eggs in the egg compartment in the refrigerator door. If possible, always store separately from other foods, as the shell is permeable to air and the eggs can take on the smell of strongly smelling foods such as onions. Do not wash the eggs before storing in order to preserve the shell's natural protective layer. It is best to store with the pointed end facing down, so they will last longer. This is because the natural air chamber is located on top of the egg. If stored the other way around, the air rises from this chamber after a while, whereby the membrane becomes detached and germs can penetrate.

Test in a water glass: is the egg still fresh?

Fresh eggs sink to the bottom in a water glass.

It is very easy to test whether a raw egg is still fresh: To do this, place the egg in a glass with cold water. A fresh egg remains on the bottom, older eggs stand up or float to the surface of the water. This is because liquid has already evaporated from an older egg through the shell and the inner cavity provides buoyancy. With a little practice, you can also tell after opening whether an egg is fresh or a bit older: With fresh eggs, the yolk and also the egg white bulge upwards, with older eggs the egg white spreads far apart, the egg yolk is flatter.

Cooking through and smelling test protect against germs

If you are not sure whether an egg is still fresh, you should boil it, fry it and cook it well. This avoids the danger of germs. Then you can easily and safely taste and smell whether an egg is still edible: What smells and tastes good is still good.

Vinegar and salt prevent bursting when cooking

The fact that eggs that have been pierced beforehand do not burst when cooking is part of the realm of cooking legends. Experiments have shown: On average, around every tenth egg breaks during cooking - regardless of whether it is poked or not. It is more helpful to add salt or vinegar to the cooking water. As a result, the escaping protein immediately coagulates and closes the break point.

Quenching reduces the shelf life of hard-boiled eggs

Only those who like their egg soft should put it off after cooking.

If you like your egg hard-boiled, you can do without quenching. The cold water does not make it easier to peel the egg, but it does reduce its shelf life. For soft-boiled eggs, on the other hand, quenching is recommended to stop the cooking process. A hard-boiled egg can be eaten in the refrigerator for about four weeks.

Hard-boiled eggs sometimes form a greenish border around the yolk. This is a chemical reaction to cooking between the iron in the egg yolk and the sulfur in the egg white. This does not change anything in terms of taste or quality.

Boiling breakfast eggs soft or hard: the cooking times

How well the shell of a breakfast ice cream can be removed after cooking depends on how fresh the egg is: the fresher, the harder it is to peel. The firmness of egg yolks and whites depends on the cooking time - which can vary slightly depending on the size of the eggs:

  • Cooking time four minutes: the egg whites and yolks are still very runny.
  • Cooking time five minutes: a firm egg white shell surrounds the soft egg yolk.
  • Cooking time seven minutes: Firm egg white and egg yolk, waxy yolk core
  • Cooking time ten minutes: egg whites and yolks are hard and can be cut without being deformed.
