What is vinegar test bite test?

The vinegar test and the bite test are two methods used to determine the quality and freshness of eggs.

The vinegar test involves adding a tablespoon of vinegar to a glass of water and then gently placing the egg in the water. Fresh eggs will sink to the bottom and lay flat, while older eggs will stand upright or even float. This is because as an egg ages, the air pocket within it gets larger, causing it to float.

The bite test involves breaking an egg open and examining the yolk and white. Fresh eggs will have a firm, rounded yolk and a thick white that doesn't spread out much. Older eggs will have flattened yolks and thin, watery whites that spread out when cooked.

Both tests are useful for determining the quality of eggs before using them in recipes. Good quality eggs will produce better results when cooking, so it's important to use fresh eggs whenever possible.
