Step 1
When buying eggs in a store, pay attention to the labeling. It must be affixed to each egg. The marking, consisting of two signs, is affixed to poultry farms.

Bring the egg to your ear and shake it. If you hear the movement of white and yolk, the product is spoiled; in a fresh egg, the yolk does not move. At home, you can determine the freshness of purchased eggs by placing them in water. If the eggs drown, they are fresh, with an age of 3-4 days, if they swim, but deep, then they were laid 7-9 days ago. Eggs floating near the surface are more than two weeks old.

Store purchased eggs in the refrigerator on the top shelf or in the door at 2-4 ° C. Fresh eggs are stored for a month, and hard boiled eggs - no more than 7 days. The surface of the egg is covered with a natural protective film that allows the egg to last longer, so wash the product immediately before cooking.
