Éclair and Cream Puff (also called Profiterole), both are French choux pastry. Éclair is an oblong pastry filled with cream or custard and topped with fondant. And, Cream Puff is a pastry ball filled with whipped cream, pastry cream, custard, or ice cream. One of my classmates said you also could make savoury cream puff, filled with salad, cream cheese or smoke salmon. It is a delicious and fresh entrée that your guests will enjoy.
Both of the pastries make from choux dough. So, what is choux dough? Choux dough is a light pastry dough made with butter, water, flour and eggs. It uses high moisture content to create steam during cooking to puff the pastry, instead of a raising agent.
