Functions of Eggs- Glazing or finishing

Glazing or Finishing:

How it works: Beaten egg is brushed over savoury pastries before baking. The egg protein coagulates with the heat and forms a shiny surface on baked products.

Example: Eggs are used to glaze savoury pastry such as vol au vents, bread dough and cheese straws to make golden when baked- this improves the finish.

Functions of Eggs- Thickening and Setting, and Tra

Thickening and Setting:

How it works: The egg protein thickens and coagulates with gentle heat.

Example: Eggs thicken custards, savoury flans, soups, sauces and quiches. They also thicken as you make omelette and scrambled egg.

Trapping Air (aeration):

How it works: Eggs trap air when they are whisked or beaten. Egg whites trap air to form a foam. This also known as aeration and lightening.

Example: This is used for choux pastry, meringues, cakes and souffles.
