1. Preparation materials: 2 potatoes, green pepper and red pepper/kloc-0 each, 3 cloves of garlic. Appropriate amount of oil, salt, garlic, soy sauce, white vinegar, pepper and chicken essence.

2. Wash and peel potatoes, slice them first and then shred them. When shredding, if the knife is not good, you can directly wipe the potatoes into uniform filaments with a silk brush. Put shredded potatoes in water, add a little vinegar and a little salt, and let stand for 15 minutes.

3. Wash the starch hidden in the potatoes. Soak potatoes in water with salt and vinegar, change them into a wave of water, put them in the refrigerator for 5 minutes, then take out the shredded potatoes and drain them.

In order to save time when standing and shredding potatoes, you can shred green peppers and red peppers and mince garlic.

5. Cook oil from the pot. When the oil is 80% hot, add minced garlic, chopped green pepper and red pepper, stir-fry for a few seconds, then add shredded potatoes and continue to stir-fry, and then add appropriate amount of salt and soy sauce. After stir-frying, add proper amount of vinegar, pepper and chicken essence, and stir-fry a few times again.
