What Came First!

Most USA supermarkets sell grade A eggs, but did you know that there are also AA grade eggs? Grade AA egg will stand up tall. The yolk is firm in the area covered by the white is small. There is a large production of thick white too thin white. Grade A egg covers a relatively small area, the yolk is round up standing the thick white is large in proportion to the thin white and stands fairly well around the yolk. Do know that there also grade B eggs; we rarely see these because they mostly go to bakeries and other food production facilities.

Have you ever cracked an egg to see a bloody spot? The blood spots are actually caused by the rupture of a blood vessel on the yolk surface during the formation of the egg. Most eggs with blood spots are removed during the grading process, but a few may escape detection.

Have you eaten a hard-boiled egg that has appeared to have a greenish ring around the yolk? The ring is harmless but it's due to an iron and sulfur compound, which forms when eggs are overcooked or not cooled quickly.

Is there a difference between brown and white eggs? No. Shell color is determined by the breed of hen and is not related to quality, nutrients, flavor or cooking characteristics. Since Brown egg layers are slightly larger birds inquired require more food, brown eggs are usually more expensive than white. Itís true that brown hens lay brown eggs and white hens white!

How long will eggs keep? Fresh eggs can be kept refrigerated in their carton for at least 4 to 5 weeks beyond the package date. Quality losses should be insignificant if the eggs are refrigerated as soon as possible after purchase.

Is it safe to eat raw eggs? The risk of food poisoning from eggs is highest with raw and lightly cooked dishes. It's best not to serve raw or lightly cooked dishes made with eggs.
What are the stringy white pieces in egg whites? These rope like pieces of egg white, called chalazae are not imperfections or beginning embryos but a natural, edible part of the egg. They keep the yolk centered in the thick white.

Are fertile eggs more nutritious? Space fertile eggs are not more nutritious than non-fertile eggs. They do not keep as well as non-fertile eggs and are more expensive to produce.

Why are some hard cooked eggs difficult to peel? Fresh eggs may be difficult to peel. Those which have been stored for a week to 10 days before cooking will usually peel more easily.

Why is an egg white sometimes cloudy or has a yellow or greenish cast to it? Cloudiness of a raw white, is due to the presence of carbon dioxide which is not had time to escape through the shell and is an indication of very fresh egg. A slightly yellow or greenish cast in a raw white indicates the presence of riboflavin.
