Production of McDonald's French fries
In fact, the French fries similar to fast food restaurants are not fried now, but the clerk just fried the finished product and heated it again. In the factory, these potatoes are also washed, screened, peeled and sliced, but there are some pretreatment methods before frying.
Generally, the cut French fries are soaked in water to remove excess starch, which can avoid the discoloration of French fries due to rapid oxidation and keep the appearance of finished products fresh.
Secondly, blanch the starched potato chips with boiling water, and then immediately cool them with cold water, so that the cold and hot operation will make the potato chips more compact. In fact, this is also a common method in Chinese kitchens.
Finally, the processed French fries are fried in an oil pan, and then the oil finally enters the freezing zone, and is quickly frozen at-15℃ to -25℃ for 10 min, and then is delivered to various stores in separate shipments, taken out when necessary, and fried again for eating.
So we can basically cut potatoes according to the gourd painting at home-soak them in water to remove starch-scald them in boiling water-take them out and put them in cold water immediately-drain them and freeze them in the refrigerator (frozen thoroughly)-just take them out and fry them thoroughly when eating. It does not need to be thawed, but it needs to be frozen hard. When fried, it is crisp outside and tender inside. Because fast food restaurants are all fried and fried twice after quick freezing, we don't need to fry once. We must drain the water before freezing in the refrigerator, otherwise the frozen ice beads will fly everywhere when frying.
I hope I can help you, but French fries are delicious, but after all, they are fried high-starch foods, so you should be moderate, otherwise you will gain weight quickly!
