【How-to】How to make crinkle cut fries

For crinkle-cut fries, simply slice potatoes vertically with a crinkle cutter, also called a wavy chopper or serrated slicer. For waffle fries, after making one vertical slice, rotate the potato 90°, and make another vertical slice. You can find many styles of crinkle-cutting tools on amazon.com for less than $10.
