Egg Basics Everything you ever wanted to know about eggs!
Structure of the Egg • Egg shell is lined with several membranes • Air pocket lies between the membranes and the shell at the wide end • As the egg ages, the air pocket grows • Inside the egg is the albumen- thick clear fluid known as the egg white • Round, yellow portion that floats within the albumen is the yolk • Chalazae anchors the yolk in the center of the egg • Twisted cordlike strands of albumen

Nutrients in Eggs • Excellent source: • protein, • riboflavin • iodine • Good source: • vitamin A, • other B vitamins • vitamin D • iron • trace minerals • Egg yolks contain saturated fat and cholesterol
Continued • Eggs are part of the meat group • 1 egg counts as 1 ounce of meat • Try not to eat more than 4 yolks a week because they are high in cholesterol • Egg whites are cholesterol free
Eggs are sold according to grade and size • Grade is determined by the inner and outer quality of the egg at the time it is packaged • Has nothing to do with freshness or size • 3 egg grades • AA and A: thicker white, used when appearance is important • B: used when appearance is not important • A is most common • No difference in nutrition value
Size • Size is determined by the minimum weight for a dozen • Recipes assume that large eggs will be used, they are the most common • Priced according to size and supply
Storing Eggs • Refrigerate in the original carton • Do not store in egg tray in the refrigerator • The drop in temperature each time the door is opened can cause the eggs to lose quality • Egg shells are porous and can pick up aromas • Do not wash before storing • Destroys the natural protective coating
Egg Size Evaluation • Based on your conclusions: • 1. How does the size of the egg reflect in cost? • 2. Why would the cost of the large brown egg be the most expensive? • 3. Using your measurements, what is the average increase in size of each egg type? • 4. Were there any significant differences in the eggs when you observed the white and yolk?
Preparing Eggs • Must be cooked at moderate temperatures for limited amounts of time • When overcooked: • Whites shrink and become tough and rubbery • Yolks will toughen and become gray-green on the surface • Can be cooked on stove, in oven, or microwave
Continued • Use medium to low heat when cooking on the stove • Time carefully to make sure they are fully cooked • The whites will coagulate- become firm, before the yolks • Yolks cook faster than the whites in the microwave • Fat draws in the heat • Remove from microwave while still moist and soft and standing time will complete the cooking
Eggs Cooked in the Shell • Place a single layer in a saucepan • Add water to at least 1 inch above the eggs • Cover the saucepan and bring the water just to boiling • Turn off heat and remove pan from heat, let stand in the hot water • Soft cooked- 4-5 minutes • Hard cooked-15 minutes (18 for xlarge)
Continued • Run cold water over the eggs to stop the cooking process • To remove the shell, gently tap the shell all over, roll egg between your hands, peel shell starting at the large end
Fried Eggs • Fry in a small amount of fat or in a nonstick skillet that is coated with cooking spray • How to fry eggs the healthy way • Heat skillet on medium high heat until a drop of water sizzles • Break an egg into a custard cup and slide into the pan (or break right into pan) • Reduce heat to low • Option is to cover the pan and cook the eggs slowly until done • Turn over to cook the other side
Baked Eggs • Also known as shirred eggs • Break into small bowl or directly into shallow baking dish, top with small amount of milk (optional) • Place in preheated 325˚F oven, bake 12 minutes for 2 eggs • To microwave: • Pierce yolk so steam can escape • Cover dish with wax or parchment paper, cut a small vent for steam to escape
Poached Eggs • Cook in simmering water • Bring water to a boil, reduce to simmer • Break egg into a small dish • Hold the dish close to the surface of the water and slip the egg in • Simmer about 5 minutes • Use a slotted spoon to lift the eggs out of the water and drain
Scrambled Eggs • Beat eggs together with water or milk • Use 1 tbsp liquid for each egg • Melt small amount of butter or cooking spray in a skillet • Pour egg mixture into hot skillet • As the mixture thickens, draw the spatula across the bottom and sides of the pan • Continue until the eggs are thickened and no liquid remains • Stirring the eggs constantly will cause them to be mushy
Scrambled Eggs in the Microwave • Cook egg mixture in a microwave safe container • Stir once or twice during the cooking process, and once at the end • Let the standing time complete the cooking
Basic Omelet • Made with beaten eggs • Cook without stirring the eggs, it will be shaped like a large pancake • Occasionally lift the edge of the omelet to allow uncooked egg to reach the bottom of the pan • When omelet is almost done, add a filling, fold in half to serve
