Canola or peanut oil, for frying
1 russet potato (about 12 oz.), cut crosswise on a mandoline or by hand into 1⁄16"-thick rounds
Kosher salt, to taste
1. Pour oil to a depth of 2" into a 6-qt. heavy-bottomed dutch oven and heat over medium-high heat until a deep-fry thermometer registers 375°.
2. Put potatoes into a strainer and rinse under cold water for 1 minute. Drain potatoes and transfer to paper towels; pat dry.
3. Working in batches, fry potatoes, stirring constantly with a slotted spoon, until light golden brown and crisp, 1–2 minutes. Using the slotted spoon, transfer chips to a rack set over a rimmed baking sheet. Season with salt.
