The document discusses different types of pastries including puff pastry, pâte brisée, and éclair paste. Puff pastry is a rich, buttery dough that bakes into hundreds of light, crispy layers through a process of rolling and folding layers of butter and dough. Éclair paste, also called pâte à choux, is used to make cream puffs and éclairs. It is leavened by steam instead of yeast and the dough is cooked before baking. Meringue is made from whipped egg whites and sugar and can be used to top pies or create baked goods.
