Puff pastry is unique in its preparation and characteristics, primarily due to the method of layering involved. It rises because of the steam created between the alternating layers of fat and dough. When baked, the moisture in the dough turns to steam, which causes the layers to expand and separate, resulting in a light, flaky texture. This method of lamination, where fat (often butter) is incorporated into the dough, allows for the creation of many delicate layers, making puff pastry renowned for its airy structure.

Regarding the other choices, puff pastry does not typically contain sugar or leavening agents like baking powder; instead, the rise relies solely on the steam created in the baking process. Additionally, while puff pastry can be used for sweet items such as mille-feuille or fruit tarts, it is not restricted to sweet pastries and is frequently employed in savory dishes as well. Lastly, the preparation time for puff pastry is relatively long due to the need for chilling the dough repeatedly and rolling it out multiple times to create the layers. Thus, the correct understanding of puff pastry centers around its distinctive preparation method that enables it to achieve its characteristic rise and texture.
