1 First, wash and peel the potatoes, and then rub them into mashed potatoes with a fine eraser.

2 Beat the prepared eggs into the mashed potatoes, add 1 tablespoon flour (not too much flour, so as not to make it soft), add appropriate amount of salt and pepper powder and stir until uniform.

Heat the pan with oil, then put the mashed potatoes into the pan, make a thin layer with a flat shovel and make it flat. Burn it for 6 minutes and then burn it on the reverse side for 6 minutes. After cooking, cut into strips.

4 cut the leek into foam, put a little salt in a bowl and simmer it with hot oil.

5 put the potato cold noodles into a bowl, put the leek (appropriate amount) and mix it evenly with vinegar. How is it? Is it simple?

Preservation method of potatoes:

Potatoes can be stored in a cool place of about 5 degrees Celsius. Never expose them to the sun or put them in the refrigerator. If the temperature is too high, potatoes will sprout or rot. If the temperature is too low, potatoes will be easily frostbitten and inedible.

Long-term storage can put potatoes and apples together, because mature apples will release a plant hormone-ethylene, which can promote the ripening of plant fruits and the shedding of organs. When potatoes and apples are put together, the ethylene produced by apples will inhibit the cells at the eye of potato buds from producing auxin, and the auxin will not germinate naturally if it does not accumulate in sufficient concentration. Mature bananas should also have this effect.

The peeled potatoes are cut into small pieces and soaked in cold water for more than half an hour, so that the remaining solanine can be dissolved in water.
