A rolling pin is a long cylindrical kitchen tool used to shape and flatten dough. It has two handles on the side, making it easier to use. Rolling pins come in different styles and materials, including rollers and rods, and can be made of wood, plastic, glass, ceramic, acrylic, bakelite, copper, brass, aluminium, silicone, stainless steel, marble, and plastic. Some rolling pins are hollow and can be filled with cold or warm water to better roll a desired food. Rolling pins of different styles and materials offer varying advantages, as they are used for different tasks in cooking and baking. Rolling pins are best used to roll out different kinds of dough such as cinnamon rolls, pizza, cookie dough, puff pastry, and scones. They ensure that the dough is evenly flattened to prevent inconsistent baking or even burning. Certain rolling pins like laser-cut or textured rolling pins have raised decorations on the surface, which are used to decorate shortcrust pastry by imprinting a pattern on the dough or to carve designs in fondant while decorating cakes. Precision rolling pins are great for accurate baking activities and include minute laser-etched lines similar to a ruler.
