Step 1: Soak the potatoes in enough cold water to cover, stir in 2 tablespoons vinegar and place in the fridge for at least 1 hour and up to 4 hours. When you refrigerate the potatoes, the starch will turn to sugar which is a good contrast to the vinegar in this recipe.
Step 2: Heat a large Dutch oven with 3 inches of oil to 325 degrees F.
Step 3: Strain the potatoes from the water and pat them completely dry. Cooking in batches, fry the potatoes in the hot oil, moving the fries with a spider or slotted spoon to keep them from sticking to each other, until the potatoes are softened and very light golden brown, about 4 minutes.
Step 4: Remove the fries onto a cooking rack and raise the oil temperature to 375 degrees F. Fry a second time until the fries are golden brown all over, 2 to 3 more minutes. Toss with the remaining 2 tablespoons vinegar, season with salt and serve.
