Then wash the potato for 5 mins with normal water to remove starch. After washing in normal water then put the potato pieces in cold water and rest it for 10 mins.
Remove it from the cold water and dry it for 5 mins in a towel. Now you have to fry the strips for 2 times for better cooking. Heat the oil and add the potato strips and let it rest for 5 mins then remove the potatoes on paper towel to absorb the excess oil.
Finally again fry the potato strips in the oil until brown, then french fries ready. Then add salt and pepper to taste and serve with sauce.
