Before frying soak the potatoes in water several times to rid them of the starch that is in them. Some home cooks who prepare French fries from scratch, cook them a single time in a generous amount of oil pre-heated to a temperature around 375 °F (190 °C, medium heat power dial settings) until they are golden and slightly crisp. The method recommended by most cookbooks, and used by many restaurants, especially those reputed to have excellent French fries, cook them in two stages: first at a thermostat temperature at around 350 °F (177 °C), until the fries are nearly cooked but still limp and pale; then, after they have been removed from the oil and allowed to cool, at a higher temperature, generally around 375 °F (190 °C), until they are golden and crisp, which normally takes less than a minute. A third method, attributed to the celebrated French chef
Joël Robuchon for the home cook, is to put the sliced potatoes into a saucepan with just enough cold oil in it to cover the potatoes, then cook them over high heat until golden, stirring occasionally.This chef mainly uses a more traditional style after blanching the cut potatoes in boiling water.
