Pastry, Desserts and Bakery Fundamentals
Pastry, Desserts and Bakery Fundamentals tests ingredient function, gluten development, lamination, custards, chocolate and baking accuracy. Expect precise ratios and process questions.
Flour and gluten
Flour protein forms gluten with water and mixing. Bread needs strong gluten; shortcrust and cakes need limited gluten for tenderness. Weigh ingredients rather than using volume for accuracy. Keep butter cold for laminated doughs and short pastry.
Lamination and baking
Lamination alternates dough and butter layers; steam in the oven separates the layers. Croissants and puff pastry require chilling between turns to keep butter from melting into the dough. Oven temperature and even loading control rise and colour.
Custards and chocolate
Custards set through egg protein coagulation; overheating causes curdling. Add hot liquid slowly to eggs to temper them. Chocolate requires tempering for snap and shine: melt, cool, then reheat to the correct working range for the chocolate type.
Worked example
Shortcrust pastry is made with cold butter, flour, a little water and salt. The butter is rubbed in until it resembles breadcrumbs, water is added sparingly, and the dough is rested in the fridge before rolling. Overmixing develops gluten and makes the pastry tough; warm butter makes it greasy.
Traps that cost marks
Overmixing pastry; using warm butter for lamination; opening the oven early; guessing measurements; and overheating custard until it scrambles.
Key points
- Weigh ingredients for accuracy.
- Overmixing develops gluten and toughens pastry.
- Keep butter cold for shortcrust and laminated doughs.
- Temper eggs before adding hot liquid.
- Chocolate must be tempered for snap and shine.
