There's nothing quite like a fat, crispy chip, fried to golden perfection. But how do you achieve that signature crunch and fluffy interior? The answer lies in the temperature of your deep fryer. The ideal temperature for cooking chips depends on whether you're frying them once or twice. For a single fry, temperatures between 160°C and 190°C are recommended for a cooking time of 5-10 minutes. However, for the ultimate chip experience, a double fry is preferred. This involves frying at a lower temperature of around 140°C for the first fry, and a higher temperature of 180°C-190°C for the second fry, resulting in a perfectly cooked chip that's crispy on the outside and tender on the inside.

The ideal temperature for frying chips is 160°C for the first fry and 190°C for the second
Frying chips is a science and an art, and getting the perfect temperature is crucial. The ideal temperature for frying chips is 160°C for the first fry and 190°C for the second. This technique ensures the signature crispy exterior and fluffy interior that makes a perfect chip.
The first fry at 160°C is intended to cook the potato through without browning it. This lower temperature softens the potato and ensures it is cooked evenly throughout. It is important to fry in batches at this stage to prevent the oil temperature from dropping. A lower temperature is also recommended for the first fry because it helps to avoid overcooking the exterior of the chip before the centre is cooked.
The second fry at 190°C is all about achieving that golden, crispy exterior. This higher temperature gives the chip its crunch and signature texture. Again, frying in batches is important to maintain the oil temperature and ensure even cooking.
The choice of potato is also important. Maris Piper, King Edward, and russet potatoes are recommended for their floury, starchy texture, which is ideal for achieving the perfect chip. The potatoes should be cut into large chips, approximately 1-1.5cm thick, or finger-sized. Soaking the potatoes in warm water before frying helps to remove excess starch and prevent discolouration.
It is also crucial to use the right oil for frying. The oil should have a high smoke point and be well-refined to prevent burning and degradation at high temperatures. Palm kernel oil is a popular choice for frying chips due to its high smoke point, neutral taste, and reusability.

Use palm kernel oil as it has a high smoke point and a neutral taste
When frying chips, it is important to use an oil with a high smoke point that is well-refined. This is because a low smoke point or unrefined oil can catch fire at high temperatures, causing a safety risk and leaving an unpleasant taste. For this reason, palm kernel oil is a good choice for frying chips. It has a high smoke point, is very well-refined, and has a neutral taste.
Palm kernel oil is derived from the flesh of oil palm fruits' kernels and is high in lauric acid. It has a sharp melting profile, making it suitable for use in confectionery fats. The smoke point of palm kernel oil ranges from 150°C/300°F to 235°C/450°F, depending on its level of refinement. A more refined oil will have a higher smoke point. Therefore, it is important to ensure that the oil is well-refined before using it for frying at high temperatures.
When frying chips, it is recommended to use a deep, wide pan or pot. The oil should be about 4 cm deep but should not fill the pan or pot by more than half. Heat the oil to the desired temperature, which will depend on the type of chip you are cooking. For thicker chips, a lower temperature of around 140°C is recommended for the first fry, followed by a higher temperature of 160°C-190°C for the second fry. For thinner chips, the oil should be heated to 320°F/160°C for the first fry and 375°F/190°C for the second.
It is important to fry the chips in small batches to prevent the oil temperature from dropping. Add the chips gently to the hot oil and fry until they are soft and pale golden, which should take about 3-8 minutes. Remove the chips from the oil and drain them on a paper towel or kitchen roll. Increase the heat to reach a higher temperature for the second fry. Fry the chips again until they are golden and crisp, which will take about 4-8 minutes. Drain and season the chips, and serve immediately.

Fry chips for 3 minutes in the first batch and 5-8 minutes in the second
To make the perfect chip, it's important to choose the right potato, oil, and salt. Maris Piper, King Edward, and russet potatoes are all great options for achieving that fluffy interior and crispy exterior. For the oil, opt for one with a high smoke point, like palm kernel oil, to prevent burning and achieve a neutral taste.
Now, let's talk about the frying process. The key to getting that signature chip shop taste and texture is to fry your chips in two batches at two different temperatures. For the first batch, heat your oil to 160°C and fry the chips for 3 minutes. This first fry at a lower temperature ensures the potatoes are cooked through and softened. It's important to fry in batches to prevent overcrowding the pan and dropping the oil temperature.
After the first batch, let the oil come back to temperature before adding the second batch. For this fry, increase the heat to 190°C and cook the chips for 5 to 8 minutes. This second fry at a higher temperature gives your chips that desirable golden and crispy exterior.
Once they're done, drain your chips and season with salt. You can also add some vinegar for an extra kick. Serve immediately and enjoy that perfect mix of soft, fluffy insides and crunchy, golden goodness!

Cut potatoes to 1-1.5 cm thickness for crispy, golden chips
To make crispy, golden chips, start by peeling your potatoes. You can leave the peel on if you like. Cut the potatoes into chips that are approximately 1-1.5 cm thick, or finger-sized. The British standard for chip shop chips is around 1 cm in thickness and 8 cm in length. However, you can experiment with the thickness of your chips and cut them to your preferred size.
After cutting your potatoes, soak them in warm water to remove the starch and prevent discolouration. This step is important as it will help you achieve crispy chips. You can also try soaking your potatoes in a brine solution or cold water with added salt to further remove the starch. If you are using a brine solution or salted water, let the potatoes soak for 15 to 20 minutes. If you are using plain warm water, soak the potatoes until the water runs clear. Then, drain and rinse the chips under cold water.
Once your chips have been soaked and rinsed, it's time to start frying. Choose an oil with a high smoke point, such as palm kernel oil, to prevent burning and maintain a neutral taste. Heat your oil to 140 degrees Celsius for the first fry. You can test the temperature using a cooking thermometer or by dropping a small piece of bread into the oil. The bread should brown in 3-4 minutes if the temperature is correct.
Now, carefully add your chips to the hot oil. Fry them for about 3 minutes, but do not let them brown. Remove the chips from the oil and let the oil come back to temperature before adding more chips. Fry your chips in batches to prevent the oil temperature from dropping and to ensure even cooking.
After frying all your chips at the lower temperature, increase the heat to 160 degrees Celsius for the second fry. You can also try frying at 180 or 185 degrees Celsius for a crispier texture. Fry the chips again until they are golden and crisp, which should take about 4 to 8 minutes.
Finally, remove your chips from the oil and drain them on paper towels or kitchen towels. Season with salt, sauce, or vinegar, and enjoy your crispy, golden chips!

Soak potatoes in warm water to remove starch and prevent discolouration
To make the perfect chips, you'll need to deep fry them at a very high temperature. This means you'll need to use an oil with a high smoke point, like palm kernel oil, which can reach high temperatures without burning.
Before frying, you should peel your potatoes and cut them into large chips, around 1-1.5cm thick, or finger-sized. Then, soak them in warm water. This will help to remove the starch and prevent discolouration. It's important to remove excess starch from your potatoes because, as studies have shown, it can be bad for your health. It can increase weight and blood pressure and may also increase the risk of heart disease.
To soak potatoes effectively, you can either use warm or cold water. If you're using cold water, simply cut your potatoes and rinse them, or soak them for a few hours. If you're using warm water, bring a pot of water to a boil first, then drop the peeled potatoes in.
Once you've fried your chips at a lower temperature of around 140–160°C to soften them, you can fry them again at a higher temperature of 180–190°C to make them crispy.
