The ultimate convenience food, eggs are powerhouses of nutrition, packed with protein and a range of 18 vitamins and minerals. They're also hugely versatile. Almost all eggs are edible but the most commonly consumed are hen's eggs. Bantam, quail, duck and goose eggs are also readily available and vary in size and flavour.
Eggs bind mixtures together as well as enriching the flavour. Beaten egg whites provide volume by trapping air.
