In pastry preparation, what effect does adding butter have on texture?

Adding butter in pastry preparation is known to significantly influence the final texture of the pastry. When butter is mixed into the flour, it coats the flour particles and inhibits gluten formation, which is essential for creating a flaky texture. The fat in butter also acts as a separator between layers of dough, leading to the development of distinct, thin layers that flake apart when baked. This results in a light, flaky pastry that is tender and desirable in various baked goods, such as croissants and puff pastries.

In contrast, other options do not accurately represent the primary function of butter in pastry making. For instance, a chewy texture typically arises from the development of gluten, which butter helps to minimize. Similarly, adding butter does not make the pastry more dense; rather, it enhances lightness and flakiness. Additionally, while butter can have a slight impact on the browning process due to its fat content, it primarily contributes to texture rather than preventing browning.
