A mandoline is a kitchen tool used for slicing fruits and vegetables with precision. It features a flat surface and a sharp blade that can be adjusted to create slices of varying thickness. This tool is popular among chefs and home cooks for its ability to produce uniform cuts quickly, making food preparation more efficient. Mandolines come in various designs, including handheld versions and larger, more stable models. They often include safety features, such as hand guards, to protect users from accidental cuts. Commonly sliced items include potatoes, cucumbers, and carrots, which can be used in dishes like salads and gratins.
