I am talking about the simple handheld cutter that you would stand a potato up on your cutting board, place the cutter on the top and use both hands to push the cutter down to the board, perfect french fries. Works like a champ, easy to clean, very inexpensive kitchen gadget to have.
I made some soups recently, two called for diced potatoes and carrots, and one for diced sausage (Vietnamese pork sausage, Cha Lua). So I decided to use the french fry cutter.
Use the cutter to make “fries” with the potatoes, carrots, and even the sausage, then just lay the fries on their side and complete the dice with a knife. This saves you a few minutes in the kitchen, and the slicer is quickly washed.
