Can we talk about my uncontrollable obsession for skinny fries. They are just so perfect. So skinny and crisp and perfectly seasoned. They are too good to pass up! Especially when seasoned with Pecorino cheese and freshly cut basil!
Peel and slice the potatoes into match-stick sized fries. Keep the potatoes in a large bowl of water while you continue to cut the remaining fries to prevent them from browning.
After peeling and slicing potatoes, place the potatoes and vinegar in a large stock pot and add 2 quarts of water and 2 tablespoons of kosher salt. Bring to a boil over high heat. Boil for 8 minutes until the potatoes are tender, but not falling apart.
Drain and spread the potatoes on paper towel-lined baking sheet and allow to dry for at least 10 minutes.
Meanwhile, heat the oil in large Dutch oven to 400°F.
Add a handful of the fries to oil, making sure the oil temperature does not drop lower than 350 degrees. Cook for 60-90 seconds, stirring occasionally with wire mesh spider strainer. After 60-90 seconds, remove them to another paper-towel lined baking sheet.
Repeat with remaining potatoes, allowing oil to return to 400°F after each addition.
Once you've fried the potatoes the first time, allow them to cool to room temperature for about 30 minutes.
Return oil to 375°F/ high heat. Fry the potatoes a second time in batches until crisp and light golden brown, about 2-3 minutes for each batch, adjusting the heat as needed to keep a consistent temperature. Once crisp. remove the fries with a wire mesh strainer and transfer to a bowl lined with paper towels and season immediately with kosher salt and pecorino cheese. Serve immediately with basil scattered on top.
Notes
You can also chill these in the fridge between frying sessions. That makes them perfect for dinner parties because a quick second dip and they are ready to go.
