Which method can help prevent a cutting board from slipping while in use?

Using a wet dishtowel or paper towel beneath a cutting board is an effective method to prevent slipping. The moisture from the towel helps to create friction between the cutting board and the countertop, keeping the board stable while you chop or slice ingredients. This technique is especially useful in home kitchens, where stability is crucial for safety when using sharp knives.

The other options may not provide the same level of effectiveness or could potentially lead to issues. For instance, while plastic wrap may hold the cutting board in place initially, it could be less reliable and may slip if not applied with enough tension. A rubber mat could offer stability, but it may not be readily available in every kitchen and could require more cleaning. Heavier boards might seem like a solution, but they can be cumbersome to handle, and their weight does not guarantee that they won't slip if the surface is slick.
