Study Notes

Understanding Eggs

Proper storage at 36ºF (2ºC) maintains egg quality for weeks, but room temperature storage quickly degrades quality.
Eggs can lose a full grade in one day at warm kitchen temperatures.
Egg size classifications include jumbo, extra-large, large, medium, small, and peewee, with corresponding weights in U.S. and metric measurements.
Cases of salmonella food poisoning from raw or undercooked eggs have led to increased awareness of egg-related sanitation concerns.
Commercial egg substitutes have been developed to reduce cholesterol, including pasteurized egg white-based substitutes and eggless options.
The most important rule of egg cookery is to avoid high temperatures and long cooking times to prevent tough eggs, discoloration, and flavor changes.
Eggs coagulate at specific temperatures depending on the type, with overcooking resulting in tough and rubbery eggs.
Whipped egg whites are used for lightness and rising power, with factors such as fat, acids, and sugar affecting foaming.
The green ring in hard-cooked eggs results from sulfur in the whites reacting with yolk iron, and can be prevented by using low temperatures and short cooking times.
Standards of quality for fried eggs include a bright, shiny appearance, compact shape, firm but tender whites, and warm, liquid yolks.
Butter is recommended for frying eggs for the best flavor, but margarine, oil, or bacon fat can also be used based on taste and budget.
Different stages of frying eggs, such as sunny side up, basted, over easy, medium, and hard, have specific characteristics regarding the setness of the yolk and white, and quality standards.
