How are recipes standardized for eggs?

Egg size: Recipes typically specify the size of the egg needed, such as large, medium, or small. This is because different sizes of eggs have different weights, which can affect the final outcome of the dish.

Egg weight: Some recipes may specify the weight of the egg in ounces or grams. This is a more accurate way to measure the amount of egg needed, as it is not affected by the size of the egg.

Egg white and egg yolk: Some recipes may call for only the egg white or the egg yolk. This can affect the texture and flavor of the dish. For example, egg whites will make a cake more airy and light, while egg yolks will make it richer and denser.

Substituting eggs: In some cases, it is possible to substitute eggs with other ingredients, such as applesauce or ground flaxseed. However, it is important to note that these substitutes will not always produce the same results as using eggs.
