Pastry is one of the most versatile components in catering. It can be used sweet or savory, as a casing, base, lid or layer. There are different types of pastry like shortcrust, flaky, puff, choux, and filo. Pastry is made from ingredients like flour, fat, water and sometimes eggs or sugar. The fat and water bind the dough while the flour provides structure. Proper mixing and handling techniques are needed to produce tender pastry. Common faults include shrinkage or uneven rising which can be caused by improper rolling, dough thickness, or baking temperature.
