Five precautions for frying French fries
2026-06-26
If you want to fry perfect French fries that are crispy on the outside and tender on the inside, and not easy to soften when cooled, you need to strictly control the following five core precautions:
1. Material selection and cutting specifications
It is recommended to choose yellow heart potatoes with high starch content, as they will have a denser texture when fried. When cutting the strips, it is necessary to maintain a uniform thickness (about 1 centimeter wide) as much as possible, which can ensure consistent heating during frying and avoid partial burning and undercooked situations.
2. Soak to remove starch and thoroughly drain
Cut potato chips must be soaked in clean water for 15-30 minutes and washed with water to remove excess free starch on the surface. This step is the key to preventing the French fries from sticking and sticking in the pan. After cleaning, be sure to thoroughly absorb the surface moisture with kitchen paper, otherwise when cooking, not only will the oil splash violently, but it will also lower the oil temperature, causing the French fries to absorb oil and become soft.
3. Blanching pre cooking and freezing shaping (key steps)
Do not directly explode. Blanch the drained French fries in boiling water with a little salt and white vinegar for 1-2 minutes (vinegar can prevent them from being cooked to perfection), then remove and thoroughly air dry. Subsequently, it is recommended to freeze it in the refrigerator for at least 2 hours. Freezing can cause internal water to crystallize and damage some cellular structures, which is the secret to creating a "crispy on the outside and empty on the inside" texture when fried.
4. Adopt the "double explosion method" for precise temperature control
It is difficult to achieve a perfect taste after frying once, and it must be done in two stages:
Initial frying (shaping and maturation): The oil temperature should be controlled at around 150 ℃, and the frying should be done for 3-5 minutes until the surface turns slightly yellow and the interior is fully cooked before removing it.
Double fry (make oil crispy): Raise the oil temperature to 180 ℃ -190 ℃, pour in the French fries and quickly fry for 30-60 seconds until golden crispy, then quickly remove. High temperature re frying can force out excess oil inhaled during the initial frying, making the skin more firm and crispy.
5. Seasoning timing and oil control
After the French fries are cooked, they should be placed on a strainer or kitchen paper to slightly control the oil, but they must be immediately salted or seasoned while they are still hot. Because the residual temperature and trace oil on the surface of French fries can help the seasoning adhere firmly; If you wait until it's completely cooled before seasoning, the seasoning will slip off directly, resulting in uneven taste.
