French fries always fail? The secret to the golden crispy texture of fast food restaurants lies in this

Step1、 Preparing ingredients: Good french fries start with choosing the right potatoes
Main materials:

4 potatoes (about 500 grams) - be sure to choose brown skinned potatoes or Russet potatoes, which have a high starch content and will be more crispy on the outside and tender on the inside when fried. Don't use those crispy potatoes (such as new potatoes), as they have too much moisture and will become soft and fluffy when fried.

flavoring:

Moderate amount of cooking oil (not exceeding the amount of French fries) - peanut oil is preferred, with a high smoke point and a particularly fragrant fried texture. If not, corn oil is also fine.

1 teaspoon salt (for seasoning)

1 tablespoon of white vinegar (this is the secret weapon to keep French fries golden!)

Enough water to soak potatoes

Step 2、 Detailed steps: Follow along, zero failure
Step 1: Processing potatoes (the key!)

After peeling the potatoes, cut them into thick slices first, and then cut them into evenly thick strips, about as thick as chopsticks. Don't cut it too finely, otherwise it will turn into shredded potatoes after frying.

Immediately put the cut potato chips into clean water and rub them twice by hand to remove the starch on the surface. This step cannot be skipped, otherwise the fries will stick together.

Change into a basin of clean water, add white vinegar, and soak for 15 minutes. White vinegar can make potatoes firmer, making them less likely to break when fried.

Step 3: First deep frying (key to shaping)
Pour oil into the pot and heat it over low to medium heat to around 130 degrees Celsius (method: throw a potato stick in and let small bubbles appear around it).
Add potato chips in batches, fry for 3-4 minutes, and remove if the surface turns slightly yellow.
At this point, the French fries are already cooked, but not crispy enough. Let it cool thoroughly on the drying rack for at least 15 minutes. If you are in a hurry, you can refrigerate for half an hour in the refrigerator. The larger the temperature difference, the more crispy it will be when fried in the end.

Step 4: Second Fry (Creating Crispy Souls)
Turn up the heat and raise the oil temperature to 180 degrees (putting potato chips in will immediately cause severe bubbling).
Add the French fries in batches again and fry for 1-2 minutes. If you see the color turn into a beautiful golden yellow and the surface is hard, immediately remove them.
Put it on a kitchen towel to absorb excess oil, sprinkle salt while it's hot, and gently shake it a few times to evenly distribute the salt.
