French fries are a beloved treat, but the key to achieving the perfect crispiness is often debated. The conventional method of making French fries involves firstly soaking the raw fries in water, followed by a double fry. The first fry is intended to cook the interior of the potato, and the second fry is to achieve the desired golden brown colour and crunchy exterior. The potatoes should be soaked in cold water for 30 minutes to an hour, or even 2-3 hours, to reduce the amount of starch and prevent premature browning. The fries should then be fried for 5 minutes at 325°F, removed to a paper towel-lined plate to sit for 5 minutes, and then fried again for 3 minutes at 375°F until golden brown.

Soak potatoes in water to prevent browning
Soaking potatoes in water before frying is a crucial step in the process of making French fries. Not only does it prevent browning, but it also reduces the formation of acrylamide, a chemical that occurs when starch-rich foods are cooked at high temperatures. Here are some detailed instructions on how to properly soak your potatoes to achieve the best results:
First, cut your potatoes into long, thin slices to create the French fry shape. As you cut them, place the potato slices in a bowl of cool water. This prevents the potatoes from browning, which is a reaction that occurs when fresh potatoes are exposed to air. Let the potatoes soak for about 30 minutes. You can also soak them for 2-3 hours or even overnight if you plan ahead, although this is not necessary. The longer soak times will further reduce the amount of starch in the potatoes, resulting in a lighter colour during frying.
After the initial soak, drain the water and rinse the potatoes for a minute using a colander. Then, place the potatoes back into a clean bowl of cool water for another 10 minutes. This second soak ensures that any remaining starch is removed. Drain the potatoes again and rinse them thoroughly. Use a kitchen towel to dry the potatoes as much as possible before proceeding to the frying step.
The frying process for French fries typically involves two stages. The first fry is done at a lower temperature (around 325°F) for about 5 minutes. This cooks the interior of the potato, making it soft. The potatoes should not take on any colour during this first fry. After the first fry, remove the potatoes from the oil and let them drain on a paper towel-lined plate for about 5 minutes.
The second fry is done at a higher temperature (around 375°F) for an additional 3-6 minutes. This step gives the French fries their signature golden brown colour and crunchy texture. Keep a close eye on the fries during this step to avoid over-browning or burning. Once they have reached the desired colour, remove them from the oil and blot with a paper towel to absorb any excess oil. Sprinkle with salt, and your French fries are ready to serve!

The double-frying method
Step 1: Soaking the Potatoes
Before frying, it is recommended to soak the potato slices in a large bowl of cold water for about 30 minutes to an hour. This helps remove excess starch and prevents premature browning during the frying process.
Step 2: First Fry
For the first fry, heat your oil of choice in a deep fryer or heavy-bottomed saucepan to a temperature between 275°F and 325°F. Add the cut potatoes in small batches, ensuring they are well-coated in oil. Fry for around 5 minutes, stirring occasionally, until the potatoes are soft but have not taken on any color.
Step 3: Drain and Rest
Remove the potatoes from the oil and drain them on paper towels or a rack. Allow them to rest for at least 5 minutes to cool down. This step helps to remove excess oil and prevent overcooking during the second fry.
Step 4: Second Fry
Increase the oil temperature to between 350°F and 375°F. Carefully return the potatoes to the hot oil and fry for an additional 2 to 6 minutes, stirring frequently. Watch them closely as they will brown quickly during this step.
Step 5: Season and Serve
Remove the potatoes from the oil once they are golden brown and crispy. Drain them on paper towels to remove excess oil, and season with salt and pepper, or your choice of spices. Serve immediately and enjoy!

Oil type and temperature
When it comes to making French fries in a deep fryer, the type of oil and temperature used play a crucial role in achieving the perfect crispy texture and flavour. Here are some insights on oil selection and temperature control for optimal French fry cooking:
Oil Type:
- Tallow: Tallow, derived from beef or duck fat, is a preferred choice for French fry enthusiasts. It has a higher smoke point than olive oil, making it suitable for high-heat frying. Tallow also imparts a superior flavour to the fries compared to soybean oil or other vegetable oils. Additionally, tallow is reusable and can be filtered for subsequent batches of frying.
- Vegetable Oils: Canola oil, peanut oil, vegetable oil, and sunflower oil are common choices for deep frying. These oils have high smoke points, making them suitable for the high temperatures required to cook French fries.
Temperature:
- First Fry: The initial frying temperature is typically around 275°F (135°C). At this temperature, the interior of the potato softens without taking on much colour. This step usually takes about 5 minutes, depending on the thickness of your fries.
- Second Fry: After the first fry, the oil temperature is increased to 350°F (175°C) to 375°F. This higher temperature crisps the exterior of the fries, giving them a golden-brown colour and crunchy texture. The second fry typically lasts for 3 to 6 minutes.
- Oil Temperature Management: It is important to maintain the oil temperature at the desired level. Overcrowding the fryer can cause the oil temperature to drop, resulting in soggy fries and prolonged cooking times. Allow the oil to return to the desired temperature before adding more potatoes.

Blotting and seasoning
Blotting
Blotting helps to remove excess oil from the fries, ensuring they are crispy and not greasy. After frying, use a slotted spoon or tongs to transfer the fries to a paper towel-lined plate. Spread them out in a single layer to allow them to "breathe" and cool down. This process helps to absorb the excess oil and prevents the fries from becoming soggy. It is important to use a fresh layer of paper towels for each batch of fries to ensure effectiveness.
Seasoning
The approach to seasoning your fries depends on personal preference and the cooking method. If you are deep-frying, it is generally recommended to season immediately after cooking while the fries are still hot. This helps the seasoning adhere better and enhances the flavor. It also allows you to easily adjust the seasoning to your liking. Common seasonings include salt, pepper, garlic powder, onion powder, paprika, and dried herbs such as parsley, oregano, thyme, and basil.
However, some people prefer to season their fries before cooking. This method can improve flavor absorption and texture. The spices penetrate the surface of the raw potatoes, infusing with their natural starches to create a more intense flavor. Additionally, seasoning before frying can contribute to a crispier texture, as salt draws out moisture from the potatoes. However, pre-seasoning has its challenges, such as the risk of over-salting or burning certain spices during the high-temperature frying process.
Ultimately, the decision to season before or after cooking is a matter of personal preference and experimentation. You can try both methods to determine which one suits your taste buds and cooking style.

Storing and reheating
Firstly, it's important to let your fries cool completely before storing them. Warm fries will create steam in the container and become soggy. Once they are cool, you can store them in an airtight container in the fridge for up to five days. You can also freeze fries for up to two months. Spread them out on a sheet pan in the freezer for 30 minutes, then transfer them to an airtight container.
When it comes to reheating, the microwave should be avoided at all costs. It will leave you with soggy, unappetizing fries. The best way to reheat your fries is in the oven at a high temperature. Preheat the oven to 400-450°F (205-230°C). Spread your fries out on a parchment-lined baking sheet, making sure they are not touching. Heat them for about eight to ten minutes, then give them a toss. If you like them crispier, bake for another two to three minutes.
If you have an air fryer, you can use that too. Preheat it to 350°F and cook the fries for three to five minutes. You can also reheat your fries in a skillet on the stovetop. Use a cast-iron skillet over medium-high heat, add a couple of tablespoons of oil, then add your fries. You can also reheat them in a countertop fryer or high-sided Dutch oven, but this requires more effort. Heat canola or sunflower seed oil to 300°F (150°C), add the fries, and fry for three to five minutes.
If you have a lot of fries, heat them in batches so that they crisp up efficiently and steam is not trapped. You can also give your reheated fries an extra boost of flavor with garlic powder, truffle oil, chopped parsley, or Parmesan cheese.
