We pour three tablespoons of the oil into the pan and when the end of a wooden spoon placed in the oil causes bubbles to rise quickly around it, we know the oil is hot. We place half of the strips into the oil and stir around with our tongs to try and keep them in one layer. After about a minute, we stir again, trying to turn any strips that are sticking out of the oil. When they are golden and crisp we remove them from the oil with our tongs and place them on a paper-towel lined plate. We immediately sprinkle them with some salt. We add a little more oil, make sure the oil is hot, and repeat with the second batch.
