Ingredient at a glance: Chicken eggs contain water, proteins, fat and emulsifiers divided between white and yolk, enabling thickening, aeration, binding and emulsification.
Flavour, Aroma and Texture
Fresh egg is mild and rich. Gentle heat produces tender curds; excessive heat causes rubbery white, dry yolk and sulphurous aroma.
How to Select It
Buy clean, uncracked eggs from an approved supply within date. Storage rules differ by country, so follow the local cold chain and label.
Professional Preparation
Wash hands after shell contact, crack each egg into a separate cup when quality matters and keep shells away from ready-to-eat food. Separate whites without passing yolk repeatedly through shells.
Best Cooking Methods
- Cook slowly for tender scramble, omelette and custard.
- Whip clean fat-free whites for foam.
- Emulsify yolk into mayonnaise or hollandaise with safe egg products.
Flavour Pairings
- Butter, cheese, herbs and mushroom.
- Tomato, spinach, potato and onion.
- Flour, sugar, chocolate and vanilla.
- Rice, lentils, chilli and soy.
Practical Substitutions
- Pasteurised liquid egg for controlled commercial use.
- Aquafaba for some foams without yolk functions.
- Tofu for savoury scramble with different texture.
Storage and Shelf Life
Store according to local regulations and package instructions, protected from temperature fluctuation and strong odours. Refrigerate cooked egg dishes promptly.
Season and Availability
A year-round ingredient, with production system and size specified on labels.
Nutrition and Dietary Context
Eggs provide high-quality protein, fat and micronutrients. Preparation and accompanying ingredients determine the complete dish.
Allergen and Food-Safety Notes
Egg is a major allergen. Raw or lightly cooked egg carries Salmonella risk; use pasteurised product for vulnerable diners or uncooked preparations as guidance requires.
Zero-Waste Use
Use surplus separated whites or yolks promptly in fully cooked recipes, freeze according to validated methods and compost shells where systems permit.
Common Mistakes to Avoid
- Cooking every egg over high heat.
- Using cracked or dirty shell eggs.
- Serving raw-egg sauce without pasteurised product and risk assessment.
Chef’s Quality Check
A cooked egg should reach the intended safe set while remaining tender; fresh raw egg should have clean odour and no shell contamination in the bowl.
