Heat vegetable oil to 375 degrees F in a large wok, Dutch oven, or deep fryer. Adjust flame to maintain temperature. Line a large rimmed baking sheet with paper towels. Fry 1/3 of tortilla wedges, using a metal spider to agitate them as they cook. Cook until bubbling slows to a trickle, chips are pale golden brown, and are very crisp, about 3 minutes. Transfer to the baking sheet and immediately season with kosher salt. Repeat with remaining batches.
