How many months does it take to master the standard potato shreds? What are your tips for shredding potatoes? My master is unwilling to teach me and I can’t find good techniques.

I have no one to teach me, I don’t know how to do it, and even ordinary chefs will think that I am a professional. Let me tell you about my personal experience. First of all, you must cut one side of the potato as a fixed surface. Then hold the potatoes with your left hand. The knife on your right hand must be steady and straight up and down. It is best to use the front half of the knife to slice the slices first. The slices must be thin. You have completed most of the whole project. Then when cutting into shreds, your left hand must hold the potato slices. This still needs to go straight up and down, from slow to fast, practice makes perfect
