The Vinegar Tip for Making Crispy Fries

Cook the fries in two batches for maximum crispiness
Once you have added the oil to your fryer, make sure the temperature reaches 160°C before adding your fries. This will cook the inside of your fries without browning them. Once they reach the top of the oil, remove them and let them sit.

For the second cooking phase, increase the temperature of your oil bath to between 180 and 190°C. Then return the fries to the fryer for about 2 to 3 minutes, until golden brown. Once they are cooked, remove them from the fryer and season them with salt according to your preferences. And now they are ready to eat!
What about cooking fries in the oven?
If you prefer not to use a fryer, or if you want to opt for a healthier alternative, you can cook your fries in the oven. Place the fries (which should first be dried with a tea towel) on a baking tray lined with parchment paper, making sure they are not touching each other. Drizzle them with a little olive oil and cook them for 25 minutes at 200 degrees Celsius. This same cooking method can also be used to make delectable parmesan zucchini fries.
