I can make simple cold onion and potato shreds.

First cut the potatoes into shreds, soak them in water for five minutes, rinse and drain.

Then cut the onions into shreds and clean them.

Pour an appropriate amount of water into the pot, boil it, add a little salt, put the shredded potatoes and onions into the pot, blanch them for 30 seconds, take them out, drain the water and put them into a plate, add Season with appropriate amount of salt, light soy sauce and chicken essence and serve.
