Dauphionise is a very rich but delicious way if preparing potatoes or similar root vegetables. You will need to slice the vegetables very thinl. This is best done with a mandolin, which is an expensive hand slicer which is extremely sharp and a great tool for preparing game chips and other thinly sliced vegetables. Alternatively, a Japanese Vegetable slicer works well, but is far less expensive that a mandolin.
