rolling pin

This term refers specifically to the kitchen tool used for flattening dough. While most are simple cylinders, some professional versions include handles at the ends or internal bearings to reduce friction during the rolling process.

Because it is a compound noun consisting of a gerund and a noun, it follows standard English countability rules for physical objects. It is typically used in the context of baking and pastry preparation, distinguishing it from other flattening tools like a tortilla press.
