Easy French Fries

Ingredients
2 1/2 pounds Yukon Gold potatoes (about 6 medium)
6 cups peanut oil
Sea or kosher salt

Directions:

1. Cover your largest baking sheet with paper towels for draining.
2. Wash and scrub potatoes, then dry.  Cut potatoes into 1/4-inch sticks. 
3. Place potatoes in heavy, deep frying pan, dutch oven or cast iron pan.
4. Add oil just to barely cover the potatoes. 
5. Turn burner to high and bring oil to a rolling boil, which will take about 5 minutes. 
6. Continue to cook, without stirring, until potatoes are limp but exteriors are beginning to firm, about 12-15 minutes. Do not stir; they will just break.
7. At 20 minute mark, gently loosen any stuck potatoes using a thong or spatula.
8. Continue to cook until crisp and golden to your liking, just about 5 to 10 minutes longer, stirring only if absolutely necessary.   
9. Using a skimmer remove potatoes from oil and spread them on the prepared sheet pan.
10. Sprinkle hot french fries with fine salt and serve immediately.

You can save the oil for later use.  It can be refrigerated and reused for future use. Stores up to 3 months.
