Anyone who does a lot of cooking would most likely agree that eggs are always an ingredient you want to have on hand, especially if you do a lot of baking.
Eggs are simple, economical, and can be prepared in a variety of ways: fried, boiled, poached, and are a necessary ingredient for many dishes and baked items.
Eggs come in different sizes, and according to USDA are sized based on their weight per dozen. The average sized egg (medium) is 49.6 grams or 1.75 ounces. The egg shell is 8 to 9 percent of the weight of the egg.
Unless referencing a specific country or a specific type of egg, the eggs mentioned in this article will be chicken eggs.
Weight Classes/Standards of Chicken Eggs
USDA has set standards for chicken egg weights and grade. The six weight classes are Jumbo, Extra Large, Large, Medium, Small, and Peewee. The standards for grade measure the appearance and quality of the eggshell as well as the quality of the yolk and the egg white, and they are rated AA, A or B.
Also, four descriptions describe the types of eggs on the market (non-cage-free, cage-free, free-range, and organic) and the standards that must be met for each type.
|Size||Grams, Per Egg||Ounces, Per Egg||Ounces, Per Dozen|
Organic eggs come from chickens that were raised outdoors without added drugs or chemicals. No genetically modified foods can be used. The chickens must live in a cage-free environment. Due to the extra costs associated with meeting the organic certification requirements, organic eggs cost a little more than commercial eggs.
The USDA requires that free-range eggs come from chickens that have some access to a small, fenced patch of cement. Free-range chickens might eat non-organic feed and antibiotics or other drugs.
