Of course, uncle should eat something hard. ...
However, I work part-time at KFC. When I came in, the French fries were semi-finished in the freezer and packed in kraft paper bags.
When frying, press the button of French fries on the French fries machine at the French fries station. When the frying time is up, the machine will beep, control the oil content of French fries, sprinkle salt twice at the French fries heating station, and shovel it evenly for 3-5 times to make the salt even. It doesn't matter.
In fact, there are two keys to this trick. One is that there are good semi-finished French fries, but the raw French fries sold in our supermarket are not good at all. The second is oil. The oil of KFC French fries is called shortening, but it is actually palm oil. This oil can make French fries crisp for a long time, and it can also make them completely fry out of water. This is our cooking oil, and the French fries fried at home are greasy and not crisp.
