This mandoline is great for making potatoes gratin dauphinois (scalloped potatoes). It sells on Amazon.ca for just over $20.
The Sterline Adjustable Stainless Steel Mandoline Slicer is super convenient and great quality for the price. Plus, like those old K-Tel ads … “It slices! It dices! It juliennes!” Also makes great waffle fries.
Has a built-in stand, and a great guard to keep fingers safe.
