Frequently Asked Questions

How do mandoline slicers work?

They are also known as the food slicers. Mandoline slicers have two surfaces that are parallel to each other to allow food to slide across one surface and meet up with the other surface that has a blade which sits parallel to the food. The blade is set at a stationary surface and adjustments are made on the surface that holds the food so that you cut it depending on the thickness you desire. The quality of the food is increased since the slicer ensures that the food cut in uniform size.

What types of cuts are made by the mandoline slicers?

The slicers can cut food depending on the thicknesses of the food you want by adjusting the width of the slices depending on how far apart are the two surfaces positioned. Also, you can make julienne cuts by changing the different styles of the slicers. To make julienne cuts, you need to use the blade that’s positioned perpendicular to the slicing blade to make uniform strips of equal sizes. Besides, the slicers come with attachment blades that you can use to make decorative cuts, such as waffle and crinkle cuts which add the quality of the food.

When used properly, the mandoline slicers don’t pose a danger to the user. It is a safe kitchen utensil. However, the slicers contain sharp blades that can injure you, so it’s advisable to use proper safety measures when operating them.

You can disassemble it to remove blades and platforms so that you clean them independently. For thorough cleanup, it is recommended to use your hands and exercise great care when handling the blades because they are incredibly sharp. Some models of the mandoline slicers are dishwasher safe but read the manufacturers specifications before immersing it in a dishwasher.
