What is the difference between choix pastry and puff pastry?
Choux pastry is used for eclairs and profiteroles and is risen by the steam expanding inside the pastry. Puff pastry is used for tarts and pies and is risen becaus eof the layers of pastry with trapped air between them, which expands when heated. The main difference is that choux pastry is just one layer, whilst puff pastry is many layers. Puff pastry tastes much more buttery, while choux pastry doesn’t taste of much.
