Cut potatoes into shreds, rinse them twice with clear water, add some flour, sesame seeds, salt and monosodium glutamate and mix well. After the ignition, put oil in the pot, fry the shredded potatoes until golden, and then leak the shredded potatoes. Put less oil in the pot, add ginger and garlic, pepper, Chili noodles, shredded potatoes and chopped green onion, and stir-fry for a while to get out of the pot. Flour is fried to make the shredded potatoes crispy outside and tender inside.
