Hot and sour potato shreds: 1. Peel and shred potatoes, and don't soak them in water, which will lose their original flavor and taste bad. You don't need green peppers, just bring some dried peppers. 2. Prepare a little minced garlic. 3. Boil the water in the pot, put the shredded potatoes and dried peppers together, and then take them out, not too long, just half a minute, and put oil in the pot.
