Peel potatoes and cut into sticks. Soak in cold salted water for 20-30 minutes. Drain well and dry well.
Heat oil to 325-350. Fry potatoes in small batches for 3-4 minutes, or until cooked through. Remove from oil and drain.
When all potatoes are fried, increase oil heat to 375 and fry a 2nd time in small batches until golden brown. Remove from oil, drain, and salt. Eat immediately.
