Zest the lime. Combine sea salt and lime zest in a small bowl.
Heat the oil in a large frying pan over medium-high heat. There should be 1/2 inch of oil.
Cut each tortilla into 6 triangles. Drop the triangles into the hot oil. When they start to turn golden around the edges (about 2 minutes), flip them over. Cook another 1 minute.
Remove onto a paper towel-lined plate. Sprinkle immediately with the lime salt.
