Cooking is an art that involves an in-depth understanding and flexible use of a variety of ingredients and spices.

Therefore, when cutting shredded potatoes, the knife should stick a little water, and rinse it with water several times after cutting, so that the starch on the surface of the shredded potatoes can be effectively removed and the possibility of sticking to the pan can be reduced. 
In addition, blanching is also the key to ensuring the taste of shredded potatoes. Blanch for no more than 20 seconds, otherwise the shredded potatoes may become soft and rotten. After blanching, remember to let it cool so that the shredded potatoes can maintain a refreshing taste. When it comes to formal cooking, hot pan with cold oil is the best choice for sautéing shredded potatoes. This will reduce the appearance of sticking pans and will also make the shredded potatoes more delicious. Ten seconds before cooking, add vinegar and stir-fry to ensure that the shredded potatoes taste the best. 
In addition to the above points, we should also pay attention to some details. For example, when cutting shredded potatoes, keep the knife sharp, and the shredded potatoes will be more neatWhen blanching, blanch quickly over high heat to keep the shredded potatoes crispyDuring the cooking process, adjust the heat and stir-fry time in time to ensure that the shredded potatoes do not stick to the pan and taste the best.
