Fresh fries are best blanched. Get a crispier finished fry by blanching potatoes in hot oil to precook before peak periods and then finish in a final fry before serving. Fries are completely cooked during the blanching stage at a lower temperature to allow the potato to cook slowly without becoming golden brown.

Why do you blanch potatoes before frying?

Blanching also works to reduce the moisture content of the French fry, helping them crisp up much more easily when fried. When the potatoes are transferred to the cold water after the hot liquid dip, the cells of the potato shrink, ensuring the fry will not absorb as much oil when it is later fried.

How long do you blanch potatoes for?

You can blanch your potatoes in portions if you have a large quantity. Leave the potatoes in the water for three to five minutes until desired tenderness. If you have a timer, start the timer as soon as you put the potatoes in the water.
