1. Preparation materials: 2 potatoes, appropriate amount of oil and tomato sauce.

2. First wash the potatoes, peel them, and then cut them into strips. When cutting into strips, cut them slightly thicker for better taste, usually about the width of two chopsticks. After cutting, wash it with clean water and put it in a basket with holes to dry for 5 minutes.

3. Now you can pour the oil into the pot. How much oil to pour depends on the number of potatoes. The oil only needs to be greater than or equal to the amount of potatoes. When pouring the oil, be sure to drain the water in the pot, otherwise Oil splashes easily. Boil the oil first. When it's a little hot, pour all the dried potatoes in and use chopsticks to turn them over from time to time. Turn over a few more times and poke the potatoes with chopsticks. If they can be poked in, it means the potatoes are cooked. Now turn off the heat and take out the potatoes to dry for 5 minutes.

4. In the last step, turn on the heat to heat the oil in the pot, then pour the potatoes in the bowl into the pot and fry them. The second frying is to make the potatoes crispy on the outside and crispy on the inside. For a tender effect, fry the potatoes until they are golden brown. A perfect French fries dish is complete. Paired with tomato sauce, it tastes like the one bought from outside.
