How to Make Delicious Frozen French Fries |
French fries in McDonald’s and KFC are all frozen french fries that need secondary fry before eating. Frozen french fries have a more attractive appearance and delicious taste due to more nutrition being kept in production.
High-quality frozen french fries with low oil have a golden brown color and crisp skin outside fresh and tender chips. The attractive color is mainly determined by blanching time and frying time, while the cooling time and frying temperature have much influence on oil content and water content.
General Making Procedure
There is no difference between making fried french fries and frozen french fries except for the final fry and freeze parts. As frozen french fries need secondary fry, the frying time should be shorter compared with fresh fried french fries.
The general frozen french fries processing steps are washing and peeling, slicing or striping, blanching, cooling and drying, frying, de-oiling, and packaging.
√ Key Points in Blanching Process
Sliced or striped potatoes need blanching before frying to remove starch and inactivate the enzyme.
Potato chips blanched in a short time will still have enzyme and they are easy to go bad. While once blanched in hot water in a long time, french fries will have poor palatability and mouthfeel. What’s more, long processing time needs more fuel and electricity increasing investment. The best blanching time for frozen french fries is 7-15 minutes at 70℃. For the different amounts of potatoes, the blanching time and water temperature can be adjusted.
√ Factors in Dehydration Process
Blanched french fries are full of water and need drying before being fried. Longer drying time, less water content. Once potatoes have much water loss, they will become hard and not tasty.
√ Important Tips in Frying Process
Frying is one important step that affects the appearance and shape of french fries. The oil content in french fries will increase heavily when potatoes are fried at low temperature in a short time and high temperature in a long time. What’s more, the color of french fries will change into dark brown if potatoes are fried in hot oil.
The best frying time for french fries is 8-10 minutes, while for thin potato chips, the frying time can be around 6 minutes. High-quality french fries usually have an oil content of 4.8%-5.7% and inner water content of 65%-70%.
