What is a common use for a rolling pin in cooking?

A rolling pin is primarily used for flattening dough, which is crucial in various baking and cooking processes, such as creating pie crusts, pastries, or pizza bases. The rolling motion and the pressure applied with the rolling pin enable the dough to be evenly spread to the desired thickness, which is essential for even cooking and proper texture in the finished product.

In contrast, whipping ingredients typically involves a whisk or an electric mixer, which incorporates air into the mixture. Chopping vegetables is best done with a knife or a food processor, as these tools allow for precise cutting. Measuring temperatures is accomplished using a thermometer, which accurately assesses the heat level of foods. Thus, the rolling pin's unique design and purpose make it particularly suited for the task of flattening dough.
